Extracting summary statistics to perform meta‐analyses of the published literature for survival endpoints

Extracting summary statistics to perform meta‐analyses of the published literature for survival... Meta‐analyses aim to provide a full and comprehensive summary of related studies which have addressed a similar question. When the studies involve time to event (survival‐type) data the most appropriate statistics to use are the log hazard ratio and its variance. However, these are not always explicitly presented for each study. In this paper a number of methods of extracting estimates of these statistics in a variety of situations are presented. Use of these methods should improve the efficiency and reliability of meta‐analyses of the published literature with survival‐type endpoints. © 1998 John Wiley & Sons, Ltd. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Statistics in Medicine Wiley

Abstract

Meta‐analyses aim to provide a full and comprehensive summary of related studies which have addressed a similar question. When the studies involve time to event (survival‐type) data the most appropriate statistics to use are the log hazard ratio and its variance. However, these are not always explicitly presented for each study. In this paper a number of methods of extracting estimates of these statistics in a variety of situations are presented. Use of these methods should improve the efficiency and reliability of meta‐analyses of the published literature with survival‐type endpoints. © 1998 John Wiley & Sons, Ltd.
