The risk of an event occurring in one group compared with another when the primary response variable is the time to event.

In biostatistics, the calculated likelihood that a particular intervention will make a study outcome more or less likely to occur. A hazard ratio of 1.0 indicates that the variable has no impact on the outcome. A hazard ratio of less than 1.0 indicates that the variable decreases the likelihood of the outcome. A ratio exceeding 1.0 indicates that the variable increases the likelihood of the outcome. A ratio of 2.0 suggests that the variable doubles the likelihood of the outcome.
