## odds

(odz),
The ratio of probability of occurrence to nonoccurrence of an event.
[pl. of odd, fr. M.E. odde, fr. O.Norse oddi, odd number]

## odds

In statistics, the probability that an event may appear or occur. This probability is estimated from known rates of occurrence of the event in a specific setting, e.g., from the known number of patients with a particular disease on a particular island. In practice most patients do not live on islands, and many have diseases whose presentation varies from the norm. The use of odds in health care always implies some degree of probability rather than of proof.

## odds

a method of expressing probability, e.g. at odds of 3 to 2 this can be converted to conventional terminology by using each number as the numerator and the sum of them as the denominator, i.e. 3/5, 2/5 or 60% or 40% or 0.6, 0.4. The odds are quoted as for or against. So that at odds of 3 to 2 the chances for an event happening are 3/5. The odds against it happening are 2/5.

posterior odds
probability determined after consideration of the results of a study.
odds ratio
the ratio, used particularly in case-control studies, estimates the chances of a particular event occurring in one population in relation to its rate of occurrence in another population.
