Which statement best captures the scope of outcomes in a cohort study?

• A. Only One Outcome
• B. Positive And Negative Outcomes; Multiple Outcomes During Follow-Up
• C. Only Positive Outcomes
• D. Only Outcomes During The First Month

Answer: (B)

In a cohort study, researchers follow a group of people over time to see what happens after exposure status is determined. The scope of outcomes is broad: you can observe multiple endpoints, and they can be both beneficial and harmful, as they occur during the entire follow-up period. This design allows you to capture the incidence of various outcomes for the exposed and unexposed groups, and more than one outcome can occur in the same person over time. That’s why statements describing a single endpoint, only positive outcomes, or outcomes limited to the early period (like the first month) don’t fit the study’s real capacity.
