In its simplest form, the hazard ratio can be interpreted as the chance of an event occurring in the treatment arm divided by the chance of the event occurring in the control arm, or vice versa, of a study.

"WebThe hazard ratio is defined as the ratio of the hazard for those who have the risk factor ( X = 1) to the hazard for those who do not have the risk factor ( X = 0). The log of the hazard ratio is. In general, the hazard ratio can be computed by exponentiating the difference of the log-hazard between any two population profiles. " - Hazard atio
