Discrepancy between ICR, AP, S and logS calculatedusing the RR and the OR for different values of R ₁₁ and R ₀₀ . The size of each bubble is directly proportional to the absolute difference in the interaction measures calculated using odds ratios and risk ratios at each value of R₁₁ and R₀₀. The line in each plot represents the set of R₁₁ and R₀₀ scenarios in which there is exact additivity (ICR = AP = 0; S = 1).
