Case control and cohort studies

The video tutorial explains the differences between case control and cohort studies, focusing on their objectives, strengths, and weaknesses. Case control studies are retrospective, quick, and cost-effective, suitable for studying rare outcomes but prone to confounding. Cohort studies are prospective, expensive, and time-consuming, allowing for the study of rare exposures and multiple outcomes, providing stronger evidence than case control studies. The video also highlights the limitations of randomized control trials in certain scenarios.
