Case-Control Studies

Case-control studies are a type of research used to identify factors that may contribute to a particular outcome, such as a disease. In this approach, researchers start with two groups: one group has the outcome (cases), and the other does not (controls). They then look back to compare differences in exposure to potential risk factors between the two groups. This method helps researchers understand what may have caused the outcome by identifying associations, but it doesn't definitively prove cause and effect. It's commonly used in fields like medicine and public health to inform prevention strategies.
