Power comparison of statistics W11, W21, W22, W23, W24, LRD and LRM (from left to right) under the bivariate exponential distribution with bivariate normal copula (BN), where Wij is the weighted win loss statistics using weight (i) for the terminal event and weight (j) for the non-terminal event in Section 4.1, LRD are the log-rank statistics based on the terminal event and LRM are the log-rank statistics based on the first event. Effect sizes for death/hospitalization are the log hazard ratios βD and βH respectively. The correlation parameter is ρ. Not all weighted win loss statistics are reported due to the space limit.
