WebAbstract. Competing risks occur frequently in the analysis of survival data. A competing risk is an event whose occurrence precludes the occurrence of the primary event of interest. In a study examining time to death attributable to cardiovascular causes, death attributable to noncardiovascular causes is a competing risk. WebPredicting the absolute risk of an event The cause-speciﬁc Cox regression models can be combined into a prediction of the absolute risk of an event of type 1 until time t conditional on the covariates x,z. For the case where K = 2 the absolute risk formula ofBenichou and Gail(1990) is given by: F1(tjx,z) = Zt 0 S(s j x,z)l1,z(sjx)ds. (2)
