Balancing events, not patients, maximizes power of the logrank test: and other insights on unequal randomization in survival trials
Godwin Yung, Kaspar Rufibach, Marcel Wolbers +2
We revisit the question of what randomization ratio (RR) maximizes power of the logrank test in event-driven survival trials under proportional hazards (PH). By comparing three app…
