Heart transplant (HTx) patients are at risk of developing renal dysfunction. Sirolimus has been used as an alternative for calcineurin inhibitors (CNI) in transplant patients with renal dysfunction. Recent data suggest that the combination of sirolim

The method of generalized estimating equations (GEE) is often used to analyze longitudinal and other correlated response data, particularly if responses are binary. However, few descriptions of the method are accessible to epidemiologists. In this pa

Suppose Var i and F i are the variance and distribution function of two random variables with mean zero, i =1,2, and r = r r and r l are the largest and smallest points, respectively, where 0 F 1 ( r )= F 2 ( r ) 1 >Var 2 ⇔{ F 1 ( t )⩾ F 2 ( t )

The method of generalized estimating equations has become almost standard for analysing longitudinal and other correlated response data. However, we have found that if binary responses have less than binomial variation over clusters, and are modelled

A Correction has been published for this article in Statisitcs in Medicine 2000; 19(21): 3017. Familiar measures of association for 2 × 2 tables are the odds ratio, the risk ratio and the risk difference. Analagous measures of outcome–exposure ass

This note is the proof of an important result for the application of random cut-points theory to the Mann-Whitney U test statistic, related directly to the Wilcoxon rank-sum statistic, used when data consist of frequencies in, for example, a 2 × k c

Conventional meta-analysis estimators are weighted means of study measures, meant to estimate an overall population measure. For measures such as means, mean differences and risk differences, a weighted arithmetic mean is the conventional estimator.

For the BVE (BiVariate Exponential) distribution, defined and explained by Marshall and Olkin (1967), the population Kendall's τ (1948), which is the probability of concordance minus the probability of discordance for a bivariate distribution, is sh

Background. Serum creatinine (Scr)-based equations lack accuracy in predicting glomerular filtration rate (GFR) in patients with liver disease. Cimetidine has been shown to improve the performance of Scr-based GFR formulae. Methods. We evaluated the
