nested case control vs case cohort studies

[@masoudhoseini6435]

Thank you for sharing this amazing video. Right from the start, I could tell that you are Iranian because of your lovely Farsi accent and the way you wrote "eighty" in Farsi 😁. By "group matching," do you actually mean frequency matching?

At 4:30 I think you meant "Prevalence of having common-flu (outcome) in the cases" and "Prevalence of smoking (exposure) in the controls".

[@medicalbasicscience4075]

Hello! Thanks for your attention. I think you may have misunderstood it, Actually, all cases do have the outcome and no control does so. Now by comparing the prevalence of smoking in case and control groups we come up with the idea wether smoking has a significant association with the outcome. If there is anything else I'd be so happy to do you a favor!!

Thank you for the video it was very informative. ولی درصد آدما که 80% بود رو با عدد فارسی نوشتید. بهتره برای بالابردن کیفیت ویدیو تغییر داده بشه

I think nested falls under cohort study

[@subhradeepsonowal6241]

Are they both hybrid studies?

[@anand001s3]

It's a hybrid design, this is what it is given as in Gordis epidemiology book

Hello deer Sonowal! thanks for commenting. In fact, stratified cross-sectional studies, nested case-control studies and case cohort studies are modified forms of the tree main study types(cross sectional, case control, cohort).
