Case-Control Study Design

A case-control study is a research method used to find out what might cause a particular health outcome, like a disease. In this design, researchers start with two groups: one group of people who have the condition (cases) and another group who do not (controls). They then look back in time to see if there were any differences in exposures or risk factors between the two groups. This helps identify potential causes or associations with the disease, providing valuable information for prevention and treatment strategies.
