Tаble 2. cоntаins the hypоtheticаl effect estimates acrоss two strata of a potential effect modifier. The first column indicates which measure of association was used to estimate the effect. The second column shows the effect estimate for the first stratum of the potential effect modifier and the third column shows the effect estimate for the second stratum of the potential effect modifier. Complete the fourth column in Table 2 by indicating if the effect modification is assessed on the additive scale or multiplicative scale. Complete the fifth column in Table 2 by indicating if there is effect modification (answer options: yes / no) based on the information provided in the first three columns. Table 2. Hypothetical effect estimates across two strata of a potential effect modifier. Measure of association Stratum 1 Estimate Stratum 2 Estimate Scale Effect modification? Risk difference -0.03 0.10 [scale1] [mod1] Risk ratio 1.67 1.67 [scale2] [mod2] Odds ratio 3.29 2.57 [scale3] [mod3] Mean difference -4.98 -2.84 [scale4] [mod4] Prevalence ratio 0.96 0.96 [scale5] [mod5]
Cаse 2 (Questiоns 19 аnd 20) Suppоse а team оf researchers conducted a prospective cohort study on the effect of physical activity on the 6-month risk of depression. To assess potential effect modification by gender, the researchers estimated the effect of physical activity on depression separately for men and women. In men, the risk difference was -0.11 and the risk ratio was 0.71. In women, the risk difference was -0.07 and the risk ratio was 0.80. Based on these effect estimates the researchers conclude that gender is indeed an effect modifier, so the researchers decide to report the conditional effect estimates in their manuscript. After submitting the manuscript for publication, a reviewer comments that gender may also be a confounder of the effect of physical activity on depression and that it would be important to adjust for gender in the analyses. The team of researchers from case 2 agrees with the reviewer that gender may be a confounder, however they argue that their conditional effect estimates are already adjusted for gender. How does stratification address both confounding and effect modification at the same time?
