My goal is to reduce educational disparities by making education FREE.
These videos help you score extra points on medical school exams (USMLE, COMLEX, etc.)
For educational purposes only; NOT medical or other advice.
Some videos contain mild profanity and hyperbole solely used to assist with memorization. Viewer discretion advised.
Opinions are entirely my own.

“Case control” start with “case”, that means we study the already diagnosed cases backwardly for risk factors; That’s how I remember the backward direction.

Love the video! Definitely helpful. I only changed thing because I may forget which direction to turn the eyes or the A. It also sticks to the usage of vowels mnemonic. So for "cAse-control" you need to look "bAckwards" and for "cOhort" you need to look "fOrward". Enjoy and Goodluck everyone!

Great tip thanks! To add to that, I noticed the second last letter in CohoRt is R for Relative risk and the second last letter in Case ContrOl is O for Odds ratio!

How to remember which way the eyes turn: in cAse cOntrOl, the eyes (O's) turn to look at the A, which is backwards/restrospective. and in cohort they look the opposite way, or prospective

I don't understand somethings. Is the only difference between a cohort and a case-control study that they are prospective and retrospective, respectively, or is there some other way to distinguish between the two. Also, why do we use Risk ratio with the former and odds ratio with the other?
