WebThe hazard ratio is used for interpreting the results of a Cox proportional hazards model and is the multiplicative effect of a variable on the baseline hazard function. For continuous predictor variables, this is the multiplicative effect of a 1-unit change in the predictor (e.g., if weight was a predictor and was measured in kilograms, it would be the multiplicative … WebThe Cox proportional hazard model . The proportional hazards model allows the analysis of survival data by regression modeling. Linearity is assumed on the log scale of the hazard.

WebA Cox model provides an estimate of the treatment effect on survival after adjustment for other explanatory variables. It allows us to estimate the hazard (or risk) of death, or other event of interest, for individuals, given their prognostic variables.
