Use of Irwin's restricted mean as an index for comparing survival in different treatment groups--interpretation and power considerations.

Abstract

In the analysis of survival data from clinical trials and other studies, the censoring generally precludes estimation of the mean survival time. To accommodate censoring, Irwin (1949) proposed, as an alternative, estimation of the mean lifetime restricted to a suitably chosen time T. In this article we consider the use of Irwin's restricted mean as an index… (More)
