The results of the paper are based on the analyses of survival data from a large clinical trial which includes more than 6,000 cancer patients. Major findings from the simulation study on power are : (1) for a heterogeneous sample, such as advanced cancer patients, a simple logrank test can yield misleading results and should not be used\uff1b\uff082\uff09the stratified logrank test may suffer some power loss when many prognostic factors need to be considered and the number of patients within stratum is small.
