WebThe floating absolute risk method provides the variance of the logarithm of the hazard ratio for each category (including the reference category) to facilitate comparisons across the different exposure categories. The boxes represent hazard ratios, with the size inversely proportional to the variance of the logarithm of the hazard ratio, and ... 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)
