The odds ratio is a statistical measure used to quantify the association between an exposure and an outcome in epidemiological studies. It is derived from a comparison of the odds of an outcome occurring in the exposed group versus the odds of the same outcome occurring in the unexposed group. An odds ratio greater than 1 indicates a positive association, while a value less than 1 implies a negative association. A value of 1 suggests no significant association between the exposure and outcome.
