Hazard Ratio HR

Health Care Term


Hazard Ratio (HR) is a statistical measure used in health care industry to compare the survival times of two patient groups, typically a treatment group and a control group. It is calculated based on a statistical model, usually the Cox proportional hazards model, which takes into account the time to an event of interest, such as death or disease progression.

The HR is defined as the ratio of the hazard rate of the treatment group to that of the control group. The hazard rate is the rate at which events occur over time, and the HR measures the relative difference in hazard rates between the two groups. An HR of 1 indicates no difference in hazard rates between the two groups, while an HR greater than 1 indicates a higher hazard rate in the treatment group, and an HR less than 1 indicates a lower hazard rate in the treatment group.

HR is commonly used in clinical trials and observational studies to assess the effectiveness of a treatment or intervention. It provides a quantitative measure of the relative risk reduction or increase associated with a particular treatment compared to a control group. HR can also be used to adjust for confounding factors that may be associated with the outcome of interest, such as age, gender, or baseline disease severity.

In summary, HR is a statistical measure used in health care industry to compare and assess the effectiveness of treatments or interventions, and to adjust for potential confounding factors. It provides a useful tool for healthcare professionals and researchers to make informed decisions about patient care and treatment.
