True or False: A disadvantage of a case-control study is the need to study large numbers of subjects.

A case-control study is designed to compare individuals with a specific condition or outcome (cases) to individuals without it (controls) to identify factors that may contribute to the condition. One of the primary advantages of this type of study is that it can be conducted with a relatively small group of subjects, especially when dealing with rare diseases or outcomes, which allows researchers to efficiently gather data about potential risk factors.

Unlike cohort studies, which often require a large number of participants to effectively track outcomes over time, case-control studies start with established outcomes and work backward, focusing on the exposures or characteristics of a smaller, targeted population. Therefore, the assertion that a disadvantage of a case-control study is the need to study large numbers of subjects is incorrect. In fact, a case-control study is commonly appreciated for its ability to provide valuable insights with fewer participants than other study designs would require. This makes the statement false.
