In statistics and epidemiology, relative risk (RR) is the ratio of the probability of an event occurring (for example, developing a disease, being injured) in an exposed group to the probability of the event occurring in a comparison, non-exposed group. Relative risk includes two important features: (i) a comparison of risk between two "exposures" puts risks in context, and (ii) "exposure" is ensured by having proper denominators for each group representing the exposure

The ratio of the outcome rate among persons exposed to a certain factor divided by the outcome rate among persons not exposed.Copyright © 2006, EUFIC - European Food Information Council. All rights reserved.
Glossary of Terms
The ratio of the incidence rate of a disease among individuals exposed to a specific risk factor to the incidence rate among unexposed individuals; synonymous with risk ratio. Alternatively, the ratio of the cumulative incidence rate in the exposed to the cumulative incidence rate in the unexposed (cumulative incidence ratio). The term relative risk has also been used synonymously with odds ratio. This is because the odds ratio and relative risk approach each other if the disease is rare (<5 percent of population) and the number of subjects is large.National Institutes of Health
Glossary of Epidemiology Terms
A comparison of the risk of some health-related event such as disease or death in two groups.
CDC Radiological Terms
the ratio between the risk for disease in an irradiated population to the risk in an unexposed population. A relative risk of 1.1 indicates a 10% increase in cancer from radiation, compared with the "normal" incidence. See also risk, absolute risk.Source: Centers for Disease Control and Prevention (CDC) ( About )

The Glossary of the American Council on Science and Health
The ratio of (1) the incidence of disease or death among individuals exposed to a risk to (2) that incidence among individuals not exposed to the same risk.
Hepatitis Central (TM) Liver Disease Medical Glossary
The proportion of diseased people amongst those exposed to the relevant risk factor divided by the proportion of diseased people amongst those not exposed to the risk factor. This should be used in those cohort studies where those with and without disease are followed to observe which individuals become diseased
a measure of comparative risk of developing a disease or condition. Statistically, RR is the chance that a person receiving an exposure will develop a condition compared to the chance that a non-exposed person will develop the same condition.Aegis
