What is the hazard ratio?

[Name] What is the hazard ratio? Hazard ratio is a number that shows essentially how well the experimental arm is doing to the standard arm. So again, that's in a comparative trial, a phase three trial again. A hazard ratio shows if the drug's better, essentially what percent better at any given time, the experimental arms doing. So, for example, let's say you have a hazard ratio of 0.5. That means your experimental arm is doing 50% better. In other words, 50% less patients will have relapsed at a given time if you're looking at the relapse rate. So it's a statistical term that kind of helps you compare how the arms are doing. [Name]
