WebThe odds ratio is a measure of association commonly used in epidemiology to quantify the relationship between an exposure and an outcome. The case-crossover study is an epidemiological design used to study the association between acute outcomes and transient exposures. Below, we provide examples of studies that apply each of these concepts. WebEXAMPLES: Calculating Ratios for Different Variables. Example A: A city of 4,000,000 persons has 500 clinics. Calculate the ratio of clinics per person. 500 ⁄ 4,000,000 × 10 n = 0.000125 clinics per person. To get a more easily understood result, you could set 10 n = 104 = 10,000. Then the ratio becomes: Example B: 10.7 ⁄ 3.8 × 1 = 2.8:1
