5. Based on the BUSPH reading, what will occur if a third variable has each of the specified impacts on the association between a specific exposure and outcome? Match each of the following scenarios to what the results of stratified analysis would look like after stratifying on levels of the third variable. . Confounding only • Effect modification only • Neither confounding or effect modification Both confounding and effect modification Descriptions: . The crude and stratum-specific measures of association will be similar to each other • The stratum-specific measures of association will be similar to each other, and the crude and the adjusted (pooled) measures of association will differ by 10% or more. • 1) Stratum-specific measures of association differ from each other, and both are greater than or both are less than the crude estimate; 2) Stratum-specific measures differ from each other, but the crude estimate is between them, so the difference between the crude and the adjusted (pooled) estimate must be determined to evaluate if confounding is present . The stratum-specific measures of association will differ from each other significantly
