Oddsis usually defined in statistics as the probability an event will occur divided by the probability that it will not occur [1]. In other words, it’s a ratio of successes (or wins) to losses (or failures). As an example, if a racehorse runs 100 races and wins 20 times, theodds...

The odds ratio (OR) is one of several statistics that have become increasingly important in clinical research and decision-making. It is particularly useful because as an effect-size statistic, it gives clear and direct information to clinicians about which treatment approach has the best odds of...

A hazard ratio might seem like relative risk ratios (RRs) and odds ratios (ORs). All these measures compare the probabilities of two groups. However, there are critical differences. For instance, RRs and ORs assess risk at one point in time, such as the end of a study. ...
