The hazard ratio is calculated by dividing the hazard rate of the event in the exposed group by the hazard rate in the unexposed group. A value of 1 indicates no difference in risk between the two groups, while values greater than 1 suggest an increased risk, and values less than 1 suggest a decreased risk. This measure is particularly useful in survival analysis and clinical trials, where the aim is to understand how different factors may influence health outcomes over time.
