Proportion Exposure Increases Disease Incidence of Diseased (Sick) Equals = Exposed Group a / (a + b) Minus - Unexposed Group c / (c + d) Odds Ratio (OR)
Case Control Studies Measures Association Between an Exposure and an Outcome Odds of Exposure in Diseased (Sick) Group a / c Divided / Odds of Exposure in Healthy Group b / d =1 Exposure does not affect odds > 1 Exposure increases disease < 1 Exposure decreases disease Specificity
