Odds ratio for the Titanic example is the relative risk and the odds ratio (OR) with 95% confidence interval (CI) were calculated OR is most often used in casecontrol studies, Relative measures of effect are risk ratio (ie the ratio between two incidence proportions), incidence rate ratio (the ratio between two incidence rates), and OR (the ratio between two odds) The risk difference is an absolute measure of effect (ie the risk of the outcome in exposed individuals minus the risk of the same outcome in unexposed) For pediatric arrest, the risk of survival if intubated during arrest was 411/1135 (36%) vs 460/1135 (41%) if not intubated Let's convert to odds and calculate an OR Intubated 411/ = 411/724 = 057 odds Nonintubated 460/ = 460/675 = 068 odds
