Both groups completed questionnaires that asked detailed questions about immediate, recent, and historic consumption of coffee and other caffeine containing beverages. Exposure: Outcome: Study DesignExplanation / Answer
Answer
EXPOSURE: consumption of coffee and other caffeine containing beverages.
OUTCOME: Myocardial Infarction
STUDY DESIGN: Case -control.
Explanation:
A case control study is a study that compares patients who have a disease or outcome of interest (cases) with patients who do not have the disease or outcome (controls), and looks back retrospectively to compare how frequently the exposure to a risk factor is present in each group to determine the relationship between the risk factor and the disease.
Case control studies are observational because no intervention is attempted and no attempt is made to alter the course of the disease. The goal is to retrospectively determine the exposure to the risk factor of interest from each of the two groups of individuals: cases and controls.
Case control studies are also known as "retrospective studies" and "case-referent studies."
In the given study,
Cases are the patients with Myocardial Infarction admitted in University Hospital.
Controls are the walk-in sports injury clinic patients.
