WebThis model satisfied the proportional hazard assumption for the subpopulation hazard being modeled, which means the general hazard ratio formula is essentially the same as for the Cox model, except a minor cosmetic difference that the betas in the Cox model is replaced by gammas in Fine and Gray’s model. Webhazard functions would also cross. Because the log-rank statistic is essentially a weighted sum of the hazard function over time, the log-rank test loses much of its power to detect the true difference in survival. Results from the Cox PH regression have the same problem. As the true hazard ratio changes over time, the estimated hazard ratio ...
