In survival analysis, the hazard ratio (HR) is the ratio of the hazard rates corresponding to the conditions described by two levels of an explanatory variable. For example, in a drug study, the treated population may die at twice the rate per unit time of the control population. The hazard ratio would be 2, indicating higher hazard of death from the treatment.

Cox regression offers the possibility of a multivariate comparison of hazard rates. However, this procedure does not estimate a "baseline rate"; it only provides information whether this 'unknown' rate is influenced in a positive or a negative way by the independent variable(s) (or covariates).

De hazard is de instantane kans om een event te krijgen, en een hazard ratio is vergelijkbaar met een relatief risico. Bijvoorbeeld: "During the 20-year follow-up, 83 women developed lung cancer. 2.
