Interpreting results: The hazard ratio - GraphPad

WebHazard Ratio (HR) = (risk of outcome in exposed group) / (risk of outcome in non-exposed group), occurring at a given interval of time 2x2 table for calculating risk Examples 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. The resolution of these endpoints are usually depicted using Kaplan–Meier survival curves. These curves … 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. For example, in a … See more Regression models are used to obtain hazard ratios and their confidence intervals.
