Estimated α level of the test for interaction based on the Tmax and χ12 statistics of STEPP competing risks endpoints in the presence of constant treatment effect: Cumulative Incidence (CUI) and Subdistribution Hazard Ratio (SHRO-E) based on O − E estimation.

The 99% interval for permutation probability value 0.01, 0.05 and 0.10 are (0.00, 0.02), (0.04, 0.06) and (0.08, 0.12), respectively.T1 represents the observed average proportion of events of interest, and Censor represents the observed average proportion censored.

Subpops. represents the average number of subpopulations. The results were based on 300 simulations of sample size N.
