   The odds ratio is a versatile and robust statistic. For example, it can calculate the odds of an event happening given a particular treatment intervention (1). It can calculate the odds of a health outcome given exposure versus non-exposure to a substance or event (2).

   The only measure of association that can be calculated in a case-control study is the odds ratio (OR) [the probability of being exposed among cases compared to the probability of being exposed among controls]. This particular odds ratio is referred to as the odds ratio of exposure.

   Following participants while waiting for incident cases of disease is expensive and time-consuming. Often, epidemiologists need a faster (and cheaper) answer to their question about a particular exposure/disease combination. One might instead take advantage of prevalent cases of disease, which by definition have already occurred and therefore requi...

   Epidemiologic data are often summarized in 2 × 2 tables. There are 2 main measures of association commonly used in epidemiology: the risk ratio/rate ratio (relative risk) and the odds ratio. The former is calculated for study designs that collect data on incidence: cohorts and RCTs. The latter is calculated for study designs that use prevalent case...

   What is odds ratio in epidemiology?

   • Odds Ratio (OR) is a fundamental concept in epidemiology and statistics, providing a measure of association between exposure and outcome across different groups. This concept is pivotal in fields like medicine, public health, and social sciences, where understanding the relationship between risk factors and outcomes can guide critical decisions.

   What are odds and relative risk in epidemiology?

   • In this manner, the results of the odds, or, the relative risk are used to assess the possible association of a risk factor in a health event (disease, or, not). For this reason, in epidemiology, the most common measures of association are the odds ratio, and the relative risk.

   What is a relative risk based on the odds ratio?

   • Answer the question based on your results of the OR. Relative Risk (commonly abbreviated as RR) It is important to understand what the relative risk is, especially when comparing it to the odds ratio. While the odds ratio assesses the risk or association in general, the relative risk is commonly used to assess causation.

   What does it mean if odds ratio is less than 1?

   • This can be seen from the interpretation of the odds ratio. An odds ratio greater than 1 implies there are greater odds of the event happening in the exposed versus the non-exposed group. An odds ratio of less than 1 implies the odds of the event happening in the exposed group are less than in the non-exposed group.
