Examples of measures of association include risk ratio (relative risk), rate ratio, odds ratio, and proportionate mortality ratio. Risk ratio Definition of risk ratio. A risk ratio (RR), also called relative risk, compares the risk of a health event (disease, injury, risk factor, or death) among one group with the risk among another group.

in a control group. The odds ratio (OR) is the odds of an event in an experimental group relative to that in a control group. An RR or OR of 1.00 indicates that the risk is comparable in the two groups. A value greater than 1.00 indicates increased risk; a value lower than 1.00 indicates decreased risk.

Analogous reasoning shows that the risk is approximately equal to the odds for the non-exposed population as well; but then the ratio of the risks, which is RR, is approximately equal to the ratio of the odds, which is OR. Förkortningen OR används ofta för den engelska termen odds ratio. Kvoten mellan två kvoter (ett annat ord för kvot är odds). Ett odds kan variera från 0 till oändligheten. Oddskvoter kan slås samman och analyseras i en metaanalys.

Whereas RR can be interpreted in a straightforward way, OR can not. A RR of 3 means the risk of an outcome is increased threefold. A RR of 0.5 means the risk is cut in half. But an OR of 3 doesn’t mean the risk is threefold; rather the odds is threefold greater.
