Efficiency of nonparametric superiority tests based on restricted mean survival time versus the log-rank test under proportional hazards
Dominic Magirr, Craig Wang, Xinlei Deng +2
Background: For RCTs with time-to-event endpoints, proportional hazard (PH) models are typically used to estimate treatment effects and logrank tests are commonly used for hypothes…
