QUESTION 19 Q19. Identify the main feature that differentiates case-control studies from cohort studies. O Case-control studies are retrospective, while cohort studies are always prospective O Randomization can be used in a cohort study, but can't be used in a case-control study O Case-control studies select subjects and group them based on disease status, but cohort studies select and group subjects based on exposure status. O Cohort studies aim to test associations, but case-control studies aim to only document the frequency of risk factors. QUESTION 20 Q20.

O Controls should be a sample of the population that gave rise to the cases, such that if a member of the control group developed the disease being studied they would have been identified as a potential case for the study. O Controls should always be present in smaller numbers than the number of cases in a case-control study. O Controls should not be exposed to the exposure of interest QUESTION 21 Q21.Which of the following are not a typical advantage of a case-control study design? In other words, identify which statement below is false about case-control studies. O They tend to be less expensive and more efficient than prospective cohort studies O They are feasible for rare diseases O They allow you to study multiple outcomes of a single risk factor O They can only be done in hospitalized populations
