Question
True or False: Case-control studies can directly measure the risk or rate of a health outcome?TrueFalse
Solution
False. Case-control studies do not directly measure the risk or rate of a health outcome. They are observational studies that compare individuals with a specific disease or outcome (cases) to individuals from the same population without the disease or outcome (controls). They can help determine if exposure to a certain factor might be associated with the disease or outcome, but they do not directly measure risk or rate.
