WebWhat is the fine gray competing risk model? Purpose: Compared with the Kaplan-Meier and Cox model, the Fine-Gray competing risk model was developed to take competing risks into account, which provides a better estimation for the risk of the main outcome of interest when one or more competing risks are presented. To date, it remains underused. WebFor example, a Fine and Gray approach may lead us to conclude that, in a given sample, with a given covariate pattern, $25\%$ of patients will die for cardiological reasons, $20\%$ of patients for other reasons, and $55\%$ will survive until the end of the follow-up.

WebNov 9, 2024 · The subdistribution hazard model by Fine and Gray (1999) is based on the proportional hazards specification by Cox (1972). In particular, it is assumed that survival times are given by random variables measured on a continuous scale. WebAs with Cox models, Fine and Gray is also based on proportional hazards. The alternative Gray’s test is a non-parametric test that does not rely on the proportional hazards assumption; however, it does not offer an effect size or the ability to adjust for confounders, analogous to the log-rank test
