The Hazard Ratio is a measure of the relative risk of an event occurring in one group compared to another. It is calculated by dividing the hazard rate of one group by the hazard rate of the other group. It is used to compare the risk of an event occurring in one group to the risk of the same event occurring in another group.

A Hazard Ratio Calculator is a tool used to calculate the relative risk of an event occurring over a given period of time. It is commonly used in medical research to compare the risk of a particular outcome between two groups of people. The hazard ratio is calculated by dividing the risk of the event occurring in one group by the risk of the event occurring in the other group.

The hazard ratio (HR) is a measure of the relative risk of an event (such as death, disease, or other outcome) in two groups over a defined period of time. It is calculated by dividing the hazard rate (or risk) of the event in one group by the hazard rate of the event in the other group. For example, if the hazard rate of death in one group is 0.2 and the hazard rate of death in the other group is 0.1, then the hazard ratio would be 2.0. This means that the risk of death in the first group is twice as high as the risk of death in the second group.
