Answer:

<em>Case Control Study </em>

Explanation:

Case Control <em>is a study comparing patients with a disease or outcome of interest (cases) with patients without the disease or outcome (controls) and looking back prospectively to compare how often the risk factor exposure is present in each group to determine the relationship between the risk factor and the disease.</em>

Case control studies are performed because there is no effort to interfere and no attempt is made to change the disease path.
