In epidemiology, a cohort study does not necessarily require a control group, as it primarily focuses on following a group of individuals (the cohort) exposed to a certain risk factor or intervention over time to observe outcomes. However, including a comparison group can enhance the study's validity by providing a benchmark for evaluating the effects of the exposure. Without a control group, it may be more challenging to attribute observed outcomes directly to the exposure. Ultimately, the design choice depends on the study's objectives and context.

What is an cohort study?
A cohort study is a type of research design where a group of individuals sharing a common characteristic are followed over a period of time to observe outcomes. By comparing outcomes between the exposed and unexposed groups, researchers can assess the impact of the particular characteristic on the outcomes of interest. This study design is frequently used in epidemiology to investigate the causes of diseases.
