Statistical power for a long-term survival trial with a time-dependent treatment effect.


A time-dependent treatment effect is often observed in cancer clinical trials with survival endpoints, especially in long-term studies. This article evaluates the statistical power of the log-rank test when change point(s) in treatment effect are given. Following the work of Schoenfeld, we derive the asymptotic properties of the log-rank test statistics… (More)
