Hazard ratio death

WebAll analyses were performed using Stata 12.0. The results of the meta-analysis were expressed as the hazard ratio (HR) or risk ratio (RR), with their corresponding 95% CI. PFS and OS were measured in terms of HR and their corresponding 95% CI. Risk ratio (RR) and corresponding 95% CIs were the summary measurement of ORR and risk of AEs. Hazard ratios are often treated as a ratio of death probabilities. For example, a hazard ratio of 2 is thought to mean that a group has twice the chance of dying than a comparison group. In the Cox-model, this can be shown to translate to the following relationship between group survival functions : S 1 ( t ) = S 0 ( t ) r … See more In survival analysis, the hazard ratio (HR) is the ratio of the hazard rates corresponding to the conditions characterised by two distinct levels of a treatment variable of interest.
