Answer:-
A case-control study is a type of observational research used in healthcare and epidemiology to compare two groups—one with a condition (cases) and one without (controls). Researchers look back to identify possible causes or risk factors by analyzing differences in medical history, lifestyle, or exposure to certain elements. These studies are useful for studying rare diseases or conditions that take years to develop. While they help identify associations, they don’t prove direct causation. Case-control studies are cost-effective and time-efficient but can be prone to bias since they rely on past data, which may not always be accurate.
