Two-stage meta-analysis of survival data from individual participants using percentile ratios
نویسندگان
چکیده
Methods for individual participant data meta-analysis of survival outcomes commonly focus on the hazard ratio as a measure of treatment effect. Recently, Siannis et al. (2010, Statistics in Medicine 29:3030-3045) proposed the use of percentile ratios as an alternative to hazard ratios. We describe a novel two-stage method for the meta-analysis of percentile ratios that avoids distributional assumptions at the study level.

One-stage parametric meta-analysis of time-to-event outcomes
Methodology for the meta-analysis of individual patient data with survival end-points is proposed. Motivated by questions about the reliance on hazard ratios as summary measures of treatment effects, a parametric approach is considered and percentile ratios are introduced as an alternative to hazard ratios. The generalized log-gamma model, which includes many common time-to-event distributions ...
متن کاملCorticosteroids improve short-term survival in patients with severe alcoholic hepatitis: meta-analysis of individual patient data.
INTRODUCTION A meta-analysis was performed using individual patient data from the five most recent randomised controlled trials (RCTs) which evaluated corticosteroids in severe alcoholic hepatitis (Maddrey discriminant function (DF) ≥ 32 or encephalopathy). This approach overcomes limitations associated with the use of literature data and improves the relevance of the study and estimates of eff...

Meta-analysis can roughly be divided into aggregate data (AD) meta-analysis and individual participant data (IPD) meta-analysis. AD meta-analysis is the traditional form of meta-analysis and fully focuses on pooling effect sizes that are formulated at the study level, i.e. this analysis represents an analysis of analyses [6]. AD meta-analysis typically combines reported summary statistics from ...

Abstract Background: Esophageal cancer is often diagnosed at a stage in which the opportunity to completely cure the patients is long gone and the patient’s survival chances are very low. Different studies have estimated very different survival times for patients suffering from esophageal cancer in different parts of the country hence there is no common estimation about the survival time for c...

Background : Meta analysis is a statistical method to combine the findings of a set of large number of published individual studies and re-analyse them. The use of meta-analysis methods in medical research has been increased, noticeably, in resent years. However, one of the major shortcomings in such analysis is that the researcher, could not access all conducted studies in the area of concern...
