Abstract
Two sample tests for right censored survival data require complicated assumptions that are sometimes not satisfied in practice. The estimated treatment effect is difficult to understand. Some papers that advocate for using the difference in restricted mean survival time, the difference in the estimated survival curves at a fixed time point, or the average difference over a pre-determined time interval, among others. The rationale for these alternative methods is that they are easier to interpret and do not require the proportional hazards assumption. The purpose of this paper is to provide some intuition for some of these tests.
