  4. Randomized controlled trial
Question 2 Multiple Choice (Single Answer)

What is the purpose of a cohort study?

  1. To investigate the relationship between an exposure and an outcome over time
  2. To compare the characteristics of two or more groups of people
  3. To estimate the prevalence of a disease in a population
  4. To evaluate the effectiveness of a new treatment
Question 3 Multiple Choice (Single Answer)

What is the difference between a case-control study and a cohort study?

  1. In a case-control study, the exposure is measured before the outcome, while in a cohort study, the exposure is measured after the outcome.
  2. In a case-control study, the participants are selected based on their disease status, while in a cohort study, the participants are selected based on their exposure status.
  3. In a case-control study, the data is collected retrospectively, while in a cohort study, the data is collected prospectively.
  4. In a case-control study, the participants are followed over time, while in a cohort study, the participants are not followed over time.
