Using the geometric average hazard ratio in sample size calculation for time-to-event data with composite endpoints
BACKGROUND: Sample size calculation is a key point in the design of a randomized controlled trial. With time-to-event outcomes, it’s often based on the logrank test. We provide a sample size calculation method for a composite endpoint (CE) based on the geometric average hazard ratio (gAHR) in case t...
