In observational studies, the researcher tests the association between a given risk factor or a therapeutic intervention under normal circumstances. These studies give us a better understanding of what can actually happens in real clinical settings rather than in controlled research facilities. As a clinician, you would need to evaluate the quality of these studies before trusting their results, and subsequently, guide your clinical-decision.
