The '''odds ratio''' is a technical term often used in medical statistics. The odds ratio is the ratio of the relative incidence of a target disorder in the experimental group relative to the relative incidence in a control group. Essentially, it reflects how the risk of having a particular disorder is influenced by the treatment. An odds ratio of 1 means that there is no benefit of treatment compared to the control group. | The '''odds ratio''' is a technical term often used in statistics, especially medical statistics and epidemiology.
