Table 2 contains the hypothetical effect estimates across 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. 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 (1 point per correct entry). 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 (1 point per correct entry).   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 0.10 0.10 [scale1] [mod1] Risk ratio 1.54 1.67 [scale2] [mod2] Odds ratio 3.29 3.29 [scale3] [mod3] Mean difference -4.98 -2.84 [scale4] [mod4] Prevalence ratio 0.96 0.96 [scale5] [mod5]

The nurse cares for a patient newly diagnosed with rheumatoid arthritis (RA). The patient states “my friend has had osteoarthritis (OA) for years. Aren’t they pretty much the same thing since both are a type of arthritis?” Think about how the nurse should respond. Identify one important difference between OA and RA that the nurse should include in the response. You may address a key difference in the diagnosis, clinical manifestations, or disease management of OA and RA. (If you identify more than one topic, I will only grade the first one).
