I explain how case control studies compare groups of individuals with and without a specific disease to identify causal associations. I also explore the design and types of cohort studies, which follow groups of individuals over time to study the relationship between exposure and disease. I highlight the importance of selecting controls and measuring exposure accurately. No specific action is requested from viewers, but understanding these study designs is crucial for conducting and interpreting epidemiological research.
