What are some examples of case-control studies?
Case-control studies are observational studies that compare individuals with a specific condition to those without it. For example, a study might compare lung cancer patients to healthy individuals to identify risk factors.
Can you give me a specific example of a case-control study?

What are the advantages of using case-control studies?
Case-control studies are cost-effective and can be conducted relatively quickly. They are particularly useful for studying rare diseases.
