A hazard ratio (HR) is the probability of an event in a treatment group relative to the control group probability over a unit of time. This ratio is an effect size measure for time-to-event data. Use hazard ratios to estimatethe treatment effect in clinical trials when you want to assess time-to-event. For example, HRs can … See more An HR is an effect measure for time-to-event data. So, let’s take a look at this data type. By understanding the data and seeing them … See more Kaplan-Meier curves graphically depict time-to-event data and really bring them to life. Consequently, analysts frequently include them to help with hazard ratio interpretation. These … See more Let’s interpret an example hazard ratio of 2.
