Abstract
This paper presents an ISO FORTRAN subroutine for determining the required sample size or power in a stratified clinical trial. The algorithm permits a post-accrual follow up period, censored observations, patient strata or risk groups, and unequal case allocation schemes. An example which illustrates use of the subroutine is provided.Keywords
