hazard ratio - (pronounced) (HA-zurd RAY-shee-oh) A measure of how often a particular event occurs over time in one group compared to the frequency in another group. In cancer research, hazard ratios are often used in clinical trials to measure the survival at any given time of a group of patients who received a particular treatment compared to a control group who received another treatment or a placebo. A hazard ratio of one means there is no difference in survival between the two groups. A hazard ratio greater than one or less than one means that survival was better in one of the groups
