Instead of using a stepwise fitting procedure symptoms 3 weeks into pregnancy order trazodone toronto, the model was fitted five times using different numbers of covariates treatment in statistics purchase trazodone with mastercard. Maximum log-likelihood values were calculated by substituting the regression coefficients with the estimates in (11 4 medications walgreens cheap trazodone 100 mg free shipping. In addition treatment vertigo buy trazodone 100mg line, subtracting the maximum log-likelihood value of fit 5 from that of fit 3 yields X:92(91316 symptoms throat cancer buy cheap trazodone on line. For a complete analysis of the data symptoms nausea order trazodone 100 mg with mastercard, the interested reader is referred to Breslow (1974). Therefore, similar to the exponential regression model, the Weibull regression model is also a special case of the proportional hazard models. The following example illustrates the use of the Weibull regression model and of computer software packages. Suppose that we wish to know if three diets have the same effect on the tumor-free time. Thus, the logarithm of the hazard ratio of rats fed a low-fat diet and those fed a saturated fat diet is log(h /h): a /, and the similar ratios J Q of rats fed a low-fat diet and those an unsaturated fat diet, and of rats fed a saturated fat diet and those fed an unsaturated fat diet are, respectively, log(h /h): a / and log(h /h): (a 9 a)/. Therefore, to test the null hypothesis that the three diets have an equal effect on tumor-free time is equivalent to testing the following three hypotheses: H: h /h: 1ora: 0, H: h /h: 1, or a: 0, J Q J S and H: h /h: 1ora: a. Failure to reject a null hypothesis implies that the corresponding log-hazard ratio is not statistically different from zero; that is, there are no statistically significant differences between the two corresponding diets. For example, failure to reject H: a: 0 means that there are no significant differences between the hazards for rats fed a low-fat diet and rats fed a saturated fat diet. When all three hypotheses H: a: 0, H: a: 0, and H: a: a are rejected, we conclude that the three diets have significantly different effects on tumor-free time. Furthermore, a positive (negative) estimated implies that the hazard of a rat fed a low-fat diet is exp(a /) times higher (lower) than that of a rat fed a saturated fat diet. Similarly, a positive (negative) estimated a and (a 9 a) imply, respectively, the hazard of a rat fed a low-fat diet is exp(a /) times higher (lower) than that of a rat fed an unsaturated fat diet, and the hazard of a rat fed a saturated fat diet is exp[(a 9 a)/ ] times higher (lower) than that of a rat fed an unsaturated fat diet. Next, place the resulting f (t,) and S(t,) in the log-likelihood G G G G function (11. The log-likelihood function for the observed 90 exact or right-censored tumor-free times, t, t. H: a: 0 (or h /h: 1), H: a: 0 (or J Q h /h: 1), and H: a 9 a: 0 (or h /h: 1) are rejected at significance level J S Q S p: 0. The conclusion that the data indicate significant differences among the three diets is the same as that obtained in Chapter 3 using the k-sample test. Q S Thus, based on the data observed, the hazard of rats fed a low-fat diet is 40% and 18% of the hazard of rats a saturated fat diet and an unsaturated fat diet, respectively, and the hazard of rats fed a saturated fat diet is 45% of that of rats fed an unsaturated fat diet. T has the lognormal distribution with the density function exp[9(log t 9) /2 ] f (t,): G (11. Two possible prognostic factors or covariates, age, and cellularfififififififififi fifififififififififi fififififi 275 Table 11. The signs of the regression coefficients indicate that age over 50 years has significantly negative effects on the survival time, while a 100% cellularity of marrow clot section also has a negative effect; however, the effect is not of significant importance to the survival time. It can be shown that T has the extended generalized gamma distribution with the density function " " Afi The estimation procedures for the parameters, regression coefficients, and the covariate adjusted survivorship function are similar to those discussed in Sections 11. There are four histological types of tumor: adeno, small, large, and squamous cell and two types of therapies: standard and experimental. Assume that the survival time follows the extended generalized gamma regression model, we wish to identify the most significant prognostic variables. First we define several index (or dummy) variables for the categorical variables and the censoring status. In particular, adeno cell carcinoma and small cell carcinoma have significant negative effects on survival time. Patients who have better Karnofsky performance status have a longer survival time. The parameter in the distribution is a function of the covariates: 1: exp 9 G: (11. Since S(t, b) is the probability of surviving longer N G than t, S(t, b)/[1 9 S(t, b)] is the odds of surviving longer than t. Therefore, the log-logistic regression model is a proportional odds model, not a proportional hazards model. The results * are similar to those obtained from fitting the general gamma regression model in Example 11. The odds of persons with large cell carcinoma are not significantly different from those of patients with squamous cell carcinoma. The model assumes that the mean survival time is linearly related to the covariates: 1 N N: a; a x: a x (11. The survivorship function (for the ith patient) adjusted for the covariates can be obtained from S (t): exp(9 t) G G N : exp 9t a x (11. Similar to the model of Feigl and Zelen (1965), a is the G underlying hazard rate when covariates are ignored, force of mortality or the intercept. Suppose that r of the n patients are dead and s: n 9 r are still alive at the end of the study; then the likelihood function is P N N L (a, a. The survivorship function for the ith individual adjusted for the covariates can be estimated from S (t): exp(9 t) G G N: exp 9t a x (11. In this section we first discuss, for a given parametric model, howto choose an optimal subset of the covariates that have statistically significant effects on the survival time. Second, we consider if the significant covariates are known, how to determine which parametric model is most appropriate. Third, we discuss a method that can be used to compare among parametric models with different subsets of covariates. Forward Selection Procedure the forward selection procedure is an adding process in which one covariate is selected and added to the model at every step. First, we have to estimate the specific parameters that define the parametric model and the coefficients of the adjusting covariates, if any, that are forced into the model. For example, to have ageand gender-adjusted results, age and gender must be included in the model, whether or not they are significant. Then the adjusted chi-square statistics for each covariate not in the model are computed and the largest of these statistics is identified. If the largest chi-square statistic is significant at the fififififi fififififififififi fififififififi 287 level specified (usually,: 0. That is, the coefficient a of x I H H satisfies X: 2[(l(a, a) 9 l(a (0))] * H H: max +2[l(a, a) 9 l(a (0))], for any x that is not in the model, I I I I (11. In the forward selection procedure, once a covariate is entered into the model, it will never be removed. The process is repeated until none of the remaining covariates meet the level specified for entry or until a predetermined number of covariates have been entered. Backward Selection Procedure the backward selection procedure is an elimination process in which all the covariates are included in the model at the beginning and are removed one by one according to a significance criterion. The specific parameters that define the parametric model and the coefficients of all the covariates are estimated first. The least significant covariate that does not meet the specified level (usually,: 0. That is, covariate x will be removed from the H model if a a X: H: min I for any x that is in the model (11. In the backward selection procedure, once a covariate H is removed from the model, it remains excluded. The process is repeated until all the covariates remained in the model meet the specified significance level for staying or until a predetermined number of covariates remain in the model. At first, it is similar to the forward selection procedure; however, covariates already in the model do not necessarily remain. Covariates already in the model may be removed later if they are no longer significant. The stepwise selection process terminates if no significant covariate can be added to the model or if the covariate just entered into the model is removed and no more covariates can be added. The procedures are exactly the same except that all the likelihood functions are replaced by those with covariates, for example, those given in (11. With computer software packages available commercially, the procedure can easily be applied. For these three fixed covariates, the log-likelihood values based on the exponential, Weibull, lognormal, loglogistic, and generalized gamma models are given in Table 11. From this table, the lognormal, Weibull and exponential models (relative to the generalized gamma model), with the three covariates, are rejected at: 0. It appears that the exponential model, relative to the Weibull, is not rejected (p: 0. However, since the exponential model belongs to the Weibull distribution family and the Weibull model has been rejected, the exponential model with the three covariates is not appropriate for the data, as noted earlier in Chapter 9. Thus, we conclude that none of the three models (exponential, Weibull, and lognormal), with covariates, provide an appropriate fit to the data. The procedure may be tedious if the number of covariates to be considered is large. However, in practice, the number of covariates worthy of consideration in a model is usually reduced after univariate analyses, as described in Section 11. With the aid of software packages, we can apply the forward, backward, and stepwise 290 fifififififififififi fififififi fififififififi fififi fifififififififififififififi fifi fifififififififififi fififififififi selection methods in Section 11. However, it is not known if the log-logistic model is significantly better than the other models. Once a specified parametric model and a G subset of covariates are selected, to assess the goodness of fit of this model, one approach is to compute the regression residuals log t 9: G G i: 1, 2. If the model fitted is correct, the corresponding G survival function G is the survival function of the fitted model. This graphical method can be used to assess the goodness of fit of the parametric regression model. The five graphs look similar, and all are close to a straight line with unit slope and zero intercept. The differences among the five distributions are small with the log-logistic distribution being slightly better than the others. Examine the relationship between survival and each of the seven possible prognostic variables as in Table 3. Estimate and drawthe survival function for each subgroup by the product-limit method and then use the methods discussed in Chapter 5 to compare survival distributions of the subgroups. Examine the relationship between remission duration and survival time and each of the nine possible prognostic variables: age, gender, family history of melanoma, and the six skin tests.

Compare the remission and survival distributions of subgroups using the methods discussed in Chapter 5. Showthat the survival time T defined by log T:; has the Weibull distribution with: exp(9 /) and: 1/ by applying the density transformation rule in (11. Showthat the survival time T defined by log T:; has the lognormal distribution by applying the density transformation rule in (11. The estimation and hypothesis testing of parameters in the models can be conducted by applying standard asymptotic likelihood techniques. However, in practice, the exact form of the underlying survival distribution is usually unknown and we may not be able to find an appropriate model. Therefore, the use of parametric methods in identifying significant prognostic factors is somewhat limited. In this chapter we discuss a most commonly used model, the Cox (1972) proportional hazards model, and its related statistical inference. The hazard function in this model can take on any form, including that of a stepfunction, but the hazard functions of different individuals are assumed to be proportional and independent of time. The important fact is that the statistical inference based on the partial likelihood function is similar to that based on the likelihood function. This means that the ratio of the risk of dying of two individuals is the same no matter how long they survive. This property implies that the hazard function given a set of covariates x: (x, x. The hazard ratio of two individuals with different covariates x and x is h(t " x) h (t)g(x) g(x):: (12. These coefficients N can be estimated from the data observed and indicate the magnitude of the effects of their corresponding covariates. For example, if there is only one covariate treatment, let x: 0 if a person receives placebo and x: 1ifa person receives the experimental drug. The hazard ratio of the patient receiving the experimental drug and the one receiving placebo based on (12. Suppose that p: 1; that is, there is only one covariate, x, which is an indicator variable: 0 if the ith individual is from group0 x: G 1 if the ith individual is from group1 Then according to (12. The hazard function of group 1 is equal to the hazard function of group0 multiplied by a constant exp(b), or the two hazard functions are proportional. In terms of the survivorshipfunction, S(t): [S (t)]A where the constant c:exp(b) (Nadas, 1970). It is now apparent that the test is based on the assumption of a proportional hazard between the two groups.

Further studies are needed to evaluate whether low cholesterol identifies a subgroup of more severely ill patients or whether infiammation and/or malnutrition were confounding variables in these studies symptoms food poisoning order generic trazodone line. Individuals with elevated cholesterol or other forms of hyperlipidemia should undergo evaluation for secondary dyslipidemias before initiation of lipid-lowering therapy [48] treatment 2011 buy trazodone online from canada. When this is not possible medications you can take while nursing cheap 100mg trazodone amex, any reduction in urinary protein excretion will be beneficial medicine buddha buy generic trazodone 100mg online. Initial treatment comprises lifestyle changes plus a low-dose statin medicine zoloft generic trazodone 100 mg on line, which is increased as needed to achieve target levels medications not to take before surgery buy cheap trazodone 100mg on line. Identification of these patients and intervention via lifestyle and/or pharmacologic therapy is a sound, initial clinical approach. Ongoing randomized trials will provide more definitive data on the risk and benefits of lipid-lowering therapy in this population of patients. These changes lead to inefiective energy generation despite adequate intake of protein and carbohydrate substrates. However, there is adequate evidence to suggest that a poor predialysis, nutritional status increases patient morbidity and mortality after initiation of renal replacement therapy [51]. Maintenance of neutral nitrogen balance is important for preservation of nutritional health in patients with chronic renal impairment. Treatment goals in this setting should be to establish and maintain optimal nutritional status, minimize uremic symptoms and signs as renal impairment declines, and to establish a nutritional plan that is acceptable to the patient. To accomplish these goals, involvement of a dietician in the care of these patients is often necessary. Serum albumin is the most extensively studied nutritional marker in all patient populations because of its easy availability and strong association with hospitalization and risk of death [52]. Non-nutritional causes of hypoalbuminemia, such as tissue injury, hepatic disease, gastrointestinal disorders, and volume overload, can afiect the specificity of this marker [54]. Moreover, given that serum albumin is a negative acute-phase reactant, its levels decrease in response to infiammatory stimuli such as burns, infection, or trauma [55]. Serum prealbumin is a sensitive marker for assessing subtle changes in visceral protein stores given its low body pool and fairly rapid turnover of 2 to 3 days. Patients with serum creatinine concentration less than 10 mg/dL should be evaluated for muscle wasting as a result of poor nutrition. Serum cholesterol concentration is an independent predictor of mortality in chronic dialysis patients, and low levels can suggest low dietary and energy intake. Serum cholesterol concentrations less than 150 mg/dL also warrant careful evaluation of nutritional status. In cases in which low protein and energy intake (as noted in patients on unrestricted diets), a dietary protein intake of less than 0. Several studies have suggested better outcomes with early initiation of hemodialysis in this setting. Additional signs that suggest need for early hemodialysis initiation include energy intake less than 20 kcal/kg/d, serum albumin concentration of less than 4. Alternative interventions may be necessary in cases when dietary counseling alone fail to optimize dietary intake. The staging system introduced in 2002 by the National Kidney Foundation is a significant accomplishment, which stratifies patients according to disease severity. With early identification and treatment of anemia, renal osteodystrophy, uremic malnutrition, hyperlipidemia, and cardiovascular disease, primary care physicians and nephrologists together are making significant strides toward extending and improving the lives of patients with chronic renal disease.

The needs of the individual patient may make it necessary to deviate from the recommendations contained in any given pathway. Although individual procedures and decision-making points within the Care Pathways have established validity or reliability, the pathways as a whole are untested. General patient education pamphlets about preventing osteoporosis should be systematically distributed to patients, women in particular but men as well. Consider offering these patients a specific evaluation and management program emphasizing detection and prevention of bone loss. The seed document was based on key articles from the literature which included current nationally based guidelines, review articles, some original studies, and descriptive articles outlining some of the standard contemporary approaches to evaluation and management of osteoporosis. The Care Pathway will be further revised at a later date, based on the results of this search and the experience of utilizing the pathway in the clinics. The term represents a diverse group of diseases with varying etiologies characterized by a reduction in bone mass per unit volume to a level below that required for adequate mechanical support and function. Pathophysiology Osteoporosis is characterized by loss in both cortical thickness and in number and size of the trabeculae of cancellous bone. The general clinical features of osteoporosis include fractures of vertebrae (lower thoracic and upper lumbar), wrist, hip, humerus and tibia, which can occur suddenly with trivial movements, as well as poor posture due to spinal deformities leading to mechanical pain. Osteoporosis can be classified into 1) groups of conditions without known etiology, 2) specific disorders which result in osteoporosis with a well understood pathogenesis, and 3) specific 1 disorders which result in osteoporosis but the pathogenesis is not understood. Peak bone mineralization in the hip is established by age 20, and peak bone mineralization of the spine is achieved in the early 30s. Osteoporosis is responsible for 240,000 hip fractures a year and 40,000 deaths annually. The rate of vertebral body fractures begins to steadily increase as patients reach their mid-60s and the rate of hip fracture rises sharply as women reach their late 70s. It is estimated that one in every 2 women over fifty will have an osteoporosis-related fracture. There is a 15% lifetime probability that a 50 year old woman will suffer a hip fracture sometime in her life. Among patients who sustain hip fractures, 12-20% die within a year after the fracture and more than 3 50% of the survivors are unable to return to independent living. Wrist or forearm fracture (Colles) is also a risk and is most commonly the result of a fall on the outstretched hand. Their total lifetime losses of bone density may reach 30-49%, and approximately one in eight will suffer an osteoporosis-related fracture. Other examples of morbidity associated with osteoporosis in both men and women are related to the shortening effect that multiple compression fractures can have on the axial length of the torso. For example, ask about family history, medical problems that occurred during the adolescent growth spurt, disorders of menstruation, severe dietary deficiencies and anorexia nervosa, physical immobilization, use of alcohol, cigarettes and chronic medication. Corticosteroids are widely used for treating patients with chronic, noninfectious inflammatory diseases such as asthma, inflammatory bowel disease, multiple sclerosis, rheumatoid arthritis, and other connective tissue disease. The most rapid bone loss occurs in the first 6 months (10-20% of bone can be lost). Patients taking low-dose inhaled corticosteroid preparations do not appear at risk. However, some data suggest that asthma patients who use inhaled corticosteroids for at least one year have an 11% prevalence of vertebral fractures. Still other data suggest that high doses of 800 micrograms or more cause bone loss. The diagnosis of osteoporosis can be made by either densitometry or by radiographs alone in the presence of a fragility fracture. Bone densitometry makes it possible to precisely and rapidly quantify the amount of bone in the spine, proximal femur, forearm, and total body while exposing the patient to a minimum of radiation. Although significantly less expensive, they measure bone mass in the forearm and wrist instead of the hip and spine and, therefore, are not recommended as a substitute for appropriate testing. Routine screening Routine screening for osteoporosis or decreased bone density in asymptomatic, 16,17 postmenopausal women is not currently recommended. There are currently no studies determining how effective perimenopausal bone density measurements are in predicting long-term fracture risk because bone mass at menopause 17 correlates only moderately with bone mass 10-20 years later. Other strong predictors of fracture include poor health, limited physical activity, poor vision, prior postmenopausal fracture, and psychotropic drug use. In one study, women who had below average bone density were more likely to take calcium, vitamins, or estrogen than those with above 19 average values (84% vs.

Stereotactic biopsy is preferred if significant morbidity can be predicted with surgery. No evidence is quoted for this approach and it is mentioned as an alternative practice rather than advocated. They recommend consideration of radiotherapy for all patients > 45 years because these tumours tend to be higher grade and have a shorter time to relapse. Explanatory note 5 below explains how this guideline uncertainty was dealt with in the radiotherapy utilisation tree. As they are not discussed in the guidelines, the use of chemotherapy has not been factored into the radiotherapy utilisation trees. Omission of chemotherapy from the tree is unlikely to make a substantial difference to the overall radiotherapy utilisation. Peterson and Cairncross stated that the large majority of patients treated with chemotherapy will relapse at a later date and subsequently need radiotherapy (23). Incidence of brain tumours Malignant brain tumours constitute 2% of all cancers in Australia in 1998 (3). The cancer registries that contribute to Australian national statistics collect information on malignant brain tumours only and do not include benign tumours such as meningiomas, craniopharyngiomas and pituitary adenomas. Radiotherapy has a role in the management of benign tumours although they are not included in the cancer statistics. Because the aim of this project is to estimate the optimum proportion of new cases of registered cancers that should receive radiotherapy at some time during the course of their illness from the best available evidence, benign diseases treated with radiation are not included. Performance status the guidelines do not specify an age cut-off for radiotherapy despite the fact that the benefits of radiotherapy, at least for highgrade astrocytomas, decrease with increasing age. There will be some patients with poor performance status in whom conservative treatment would be considered the most appropriate. Determining this performance status cut-off is difficult with little data available to provide an appropriate cut-off. Therefore, surrogate data was used to determine the proportion of high-grade glioma patients in whom radiotherapy would not be appropriate given their poor performance status. The South Australian Hospital Registry registered 1035 brain tumours from 1977-1998 (4). Of these cases, 94% had some form of primary therapy (largely surgery and/or radiotherapy). We presume that this was based on age/co-morbidity although the specific reasons for omission of therapy are not known and the appropriateness of a conservative treatment approach is also not known. Incidence by histological type A number of studies have been published on the incidence of various types of brain tumours. Some studies include data on benign conditions and brain metastases; in these instances the incidence has been recalculated by removing the data on benign and metastatic cases. They proposed that this was a better method than by using hospital inpatient data sources as not all brain tumours are treated or referred to specialist units within the county areas. However, no description is available to indicate the proportion of astrocytomas with low-grade histology. Age There are 2 aspects to age that might impact upon the decision to deliver radiotherapy: a) Older patients with brain tumours have a particularly bad prognosis and there will be clinical situations where conservative supportive care rather than radiotherapy (+/surgery) is chosen. However, age alone is not necessarily a sensitive enough measure for appropriateness of treatment (see explanatory note 2 on performance status above). With reference to gliomas in the radiotherapy utilisation tree, we used performance status rather than old age as a determinant of whether an elderly patient with glioma was appropriately treated with radiation. It is beyond the scope of this project to review all of the literature for and against post-operative therapy for completely resected lowgrade glioma. The first completed randomised trial comparing surgical resection alone versus surgical resection and post-operative radiotherapy in low-grade glioma has completed patient recruitment. The interim trial results at a median follow-up of 5 years have been reported by Karim et al (14). They found that post-operative radiotherapy significantly improved the time to progression but there was no statistically significant improvement in overall survival. The authors conclude, based on their findings, that post-operative radiotherapy should be used to delay recurrence. Some retrospective reviews suggest superior outcome for patients undergoing immediate post-operative radiotherapy compared with radiotherapy delayed until recurrence. They found no dose response for radiotherapy raising the possibility that there is little effect. They advocate chemotherapy as the postoperative treatment of choice and suggest use of radiotherapy for recurrence. However, they concede that the majority of cases will ultimately recur after chemotherapy. As stated previously, the guidelines suggest observation or radiotherapy with little discussion about chemotherapy for oligodendroglioma. All patients > 45 years with completely resected oligodendroglioma or low-grade glioma (a very small sub-group) are indicated to undergo radiotherapy because the guidelines suggest that these tumours are more aggressive in the older age group. All patients < 45 years of age were recommended to undergo observation with radiotherapy for recurrence. However, the alternative view that all patients irrespective of age should be given radiotherapy was factored into the tree by changing the proportion of people < 45 years to 0% in the sensitivity analysis. They used an age cut-off of 40 years; 47% of their patients were above the age of 40 years. Therefore in this study, 50% of patients are assumed to be <45 years and hence undergo observation and only receive radiation at recurrence. The data was then modelled by varying the proportion of patients <45 years to 0% to indicate that all patients receive radiotherapy at diagnosis. Proportion of pilocytic astrocytomas that are not completely resected Desai et al. They had a complete resection rate, proved by a negative post-operative scan, of 69%. Due to the large discrepancy in the data we used a total resection rate of 82% from the largest series (Desai et al. Proportion of completely resected pilocytic astrocytomas that recur Krieger et al. The two trials included in the analysis were trials assessing the timing and dose of radiation therapy required for lowgrade gliomas. Of the entire data set of 610 patients, 206 (34%) were quoted as having had resection of 90-100% of the low-grade glioma. In addition, a lot of the old studies had follow-up periods of < 5 years which is an inadequate duration for a determination of the true recurrence rate. Furthermore, the reports identify that a proportion of the study population had radiotherapy and others did not; however the recurrence data is not reported in accordance with the completeness of excision and the omission of radiotherapy. The recurrence data is usually presented in a univariate fashion or only as overall survival data, without providing any disease-specific or local recurrence data. These data are multi-institutional in that multiple departments contributed to the study as opposed to using single institutional data. However, this study does include a small proportion of patients who had less than a complete resection although the investigators were prepared to allow these patients the possibility of being randomised to no radiotherapy. The recurrence rate for this group was 85/140 (61%) at a median follow-up of 5 years. Proportion of oligodendrogliomas that undergo complete excision the best data source was from Lindegaard et al. They found that of the 175 evaluable cases, 43 (25%) were totally resected and the other 75% had subtotal resection. This study was considered superior to other studies that were evaluated, which are single institutional studies. Proportion of completely-resected oligodendrogliomas treated by surgery alone that recur Lindegaard et al. Bullard reported that of the 24 patients treated with surgery alone in their series, with long-term data available, 54% have recurred (18). There were two areas in the tree where either the data or the evidence to support radiotherapy were uncertain. The authors conclude by recommending radiotherapy to all patients, although advocates for delayed radiation suggest that the lack of an overall survival benefit shows that delayed radiotherapy (with or without other therapy such as surgery or chemotherapy), may be effective. Firstly, because the guidelines suggested that radiotherapy be omitted for completely resected, low-grade, < 45 years (approximately half the patients are <45 years), then the tree indicates that they do not receive radiation. However, the other scenario was that the proportion getting radiotherapy due to age was re-set at 1. The second controversy was the complete resection data rates for pilocytic astrocytoma. There was considerable difference between the largest series (82%) and the next three largest series. The data analysis incorporated sensitivity analysis using data from the two largest series. Another area where the data varied was for the complete resection rates for oligodendroglioma. However, this was not included into the sensitivity analysis because the best evidence was higher in the hierarchy of evidence as described in the study outline and therefore the best data source was used.
