Web1 Apr 2024 · The cumulative incidence of failure was estimated as a function of postoperative day (POD), with death as a competing event according to the Fine and Gray model. No events were censored with the assumption that this population would not relocate from the state, and hence both death and failure would be detected. ...

WebSurvival models can be viewed as consisting of two parts: the underlying baseline hazard function, often denoted , describing how the risk of event per time unit changes over time at baseline levels of covariates; and the effect parameters, describing how the hazard varies in response to explanatory covariates. Web1 Jul 2024 · Specifically, we consider the class of discrete subdistribution hazard models, which directly relate the cumulative incidence function of one event of interest to a set of covariates. We...
