Method 1a: Cox PH model, censor death at the time of death;
Method 2a: Log rank test, censor death at the time of death;
Method 3a: Test the Restricted Mean Survival Time (RMST) difference, censor death at the time of death;
Method 1b: Cox PH model, censor death at Day 28;
Method 2b: Log rank test, censor death at Day 28;
Method 3b: Test the Restricted Mean Survival Time (RMST) difference, censor death at Day 28;
Method 4: Subdistribution hazard model;
Method 5: Test cumulative incidence function (CIF) difference using a modified log-rank Chi-square test;
Method 6: Test the difference of the area under the cumulative incidence function (CIF) curve.
Note: Hazard ratio > 1 in Methods 1a and 2a, Ratio of RMST<1 in Methods 2a and 2b, Subdistribution hazard ratio > 1 in Method 4, and Ratio of CIF AUC >1 in Method 6 indicate treatment benefit.
