The competing risk regression provides a subdistribution hazard ratio (SHR) that assesses the primary “net effect” size which is the chance of the lower-threshold group compared with the higher-threshold group for the particular event (ECMO removal, weaning from mechanical ventilation, stopping sedation, SOFA score < 6, stopping renal replacement therapy, stopping vasopressors) accounting for the existence of the alternative outcome of death. The hazard ratio is the ratio of (chance of an event occurring in the treatment arm)/ (chance of an event occurring in the control arm) (20).The HR has also been defined as, the ratio of (risk of outcome in one group)/ (risk of outcome in another group), occurring at a given interval of time (21) When interaction terms are included in a Cox Proportional Hazards model, it is very tricky to compute the hazard ratio (HR) and, especially, the confidence intervals. The rate is referred to as the subdistribution hazard. That term might cause confusion with the cause‐specific hazard and it can be considered the hazard only of something that violates the three principles of Andersen and Keiding (2012), but we will the term nevertheless because it is well‐established in the literature.

In contrast to cause-specific hazard modeling, this approach has the advantage that only one model needs to be considered for interpretation; on the other hand, it does not provide insight in the characteristics of the cause-specific hazard The subdistribution hazard (SDH) for death is given at the bottom of the figure along with the cause-specific hazard (CSH) for death for comparison. Note that, because individuals are maintained in the risk set, the SDH of the event of interest tends to be lower than the CSH (adapted from Lau et al. [ 6 ]). The subdistribution hazard function for a given type of event is defined as the instantaneous rate of occurrence of the given type of event in subjects who have not yet experienced an event of that type. 3 Note that the risk set consists of those subjects who are either currently event‐free or who have previously experienced a competing event. In subsequent discussions, it will be important to recall that subjects who experience a competing event remain in the risk set. Subdistribution Hazards The subdistribution hazard, h ks (t), is the instantaneous risk of dying from a particular cause k given that the subject has not died from cause k. h ks (t) = lim t!0 n P(t T<t+ t;K=kjT>t or (T t & K6=k) t o Sally R. Hinchli e University of Leicester, 2012 22 / 34 Conversely, the subdistribution hazard ratio may be thought of as a measure of ‘prognostic association’, i.e. best suited to quantifying predictive relationships [ 30 ]. The proportional cause-specific hazard assumptions of the Cox-PH and Lunn-McNeil models are assessed using Schoenfeld residuals [ 31 ]. The cumulative incidence function (CIF), which is the marginal failure subdistribution of a given cause, is widely used in competing-risks analysis. The proportional hazards model for the subdistribution that Fine and Gray propose aims at modeling the cumulative incidence of an event of interest. They define a subdistribution hazard,
