risk ratio - measure of the risk of a particular event occurring in one group compared to the risk of the same event occurring in another group. In cancer research, risk metrics are used in prospective (future-oriented) studies such as cohort studies and clinical trials. A risk ratio of one means that there is no difference between two groups in terms of their cancer risk, based on whether or not they were exposed to a particular substance or factor, or how they responded to two compared treatments. A risk ratio greater than one or less than one usually means that exposure to a particular substance or factor either increases (risk ratio greater than one) or decreases (risk ratio less than one) the risk of cancer, or that treatments are being compared not the same effects. Also called relative risk
