Web2 days ago · A univariate Cox regression analysis of survival among each subgroup and the overall population was conducted after the classification tree was generated. Based on the overall population as a baseline, we calculated relative hazard ratios (RHRs) for recurrence or mortality in subgroups, and the ranking of the RHRs was used to determine ... WebJan 1, 2007 · Cox’s regression model is widely used for analyzing survival data under competing risks as well as for single risk. We consider situations in which failure times are observed but failure types...
