Differentiate between case control and Cohort Study with suitable example.

A case-control study and a cohort study are both observational research designs used in epidemiology to investigate associations between exposures and outcomes, but they differ significantly in their approach, timing, and the way data is collected. Understanding these differences is crucial for selecting the appropriate study design in the context of Occupational Health and Safety (OHS) research.

Case-Control Study:

A case-control study is a retrospective study design that starts with identifying individuals who have a specific outcome or disease (cases) and comparing them with individuals who do not have the outcome (controls). The goal is to examine whether an exposure or risk factor was more prevalent in the cases compared to the controls.
