  1. Methods included: log-rank type (LRt), semi-parametric additive model (sAM), fully parametric additive model (fAM), log-rank test in hypothetical world (LRh). ((im)bal = (im)balanced variable, i.e., the groups occur with (un)equal probabilities; bin= binary variable; 4 grps = a variable with four groups). X is the categorical covariate of interest, D denotes the demographic variables
