Case Control vs. Cohort Study || USMLE

[@estherxu7263]

“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.

[@sarscov_3covid-214]

I wish you nothing but success and happiness in your life.

[@KoticMuziK]

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!

[@silvergray5981]

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!

[@adamjenkins3130]

I really liked your memory tool

[@babygurll7]

@@silvergray5981 @koticinyomouf YOU TWO ARE AMAZING! Thank you!!

[@Reemessi1]

Thx for ur idea 😍😍amazing!

[@LilDroov]

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

[@Tyse723]

case cOntrOl also has two O's too. ¯\_(ツ)_/¯

[@andrea-anncaravana4291]

fOrward=cOhort;bAckwards=cAse control

[@deboo117]

I just facepalmed myself on that cohort mnemonic

How to differentiate between case cx and prospective cohort?

[@graciesessions3154]

Is there a part 2??

[@hannahvansumeren4196]

Hey Can you make a video on the bilirubin pathologies? Dubin, Gilberts, Rotor, etc? It would be awesome!

[@dancequeen1080]

best video on youtube. idc. YOU SAVED ME THANK YOU!

[@mandijelinek3402]

I literally owe you my now passing grade. Can you make one for ecological studies, cross-sectional studies, randomized and non-randomized clinical trials??

[@perseusgeorgiadis7821]

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?

[@mahbubhasantonmoy5555]

According to me, it is the best explanation!

[@rocktune2719]

so helpful..wish i had watched this during my college exams

[@xxxgooglexxx]

probably will never forget, beautifully explained

[@ostcx]

this is the best vid ever like am not joking. this sparks joy

[@Inquisitive-herr]

But how will we differentiate between a case control retrospective and cohort retrospective 😥

[@taniamukherjee8590]

I think you mean case control and cohort retrospective? You're still looking at relative risk, just that it happened in the past.

[@lanaakhras4909]

Thank you !!!! Please do more Biostats

[@charlespeter9914]

Am interested in canine parvovirus which is cause of gastroenteritis in dogs, so i want to sample only dogs with signs of vomiting/diarrhoea. what type study is this?

[@peninapearl6491]

where can i get rest videos on biostat pl?

[@sabeaniebaby]

I laughed my head off ... and in the end, yes, very helpful.

CASE CONTROL STUDY ARE RESTROSPECTIVE STUDY WHILE COHERT ARE PROSECTIVE STUDY

[@MOTM1234]

Well, cohorts can also be Retrospective, so don’t get caught slipping

[@diamondbloom6918]

[@pratiksha8150]

I'm an IMG from india and plan on taking the exam in December 2016.Are you sure that retrospective cohort study are not tested on the step 1??..I'm really confused with retrospective cohort and case-control study!!..please do let me know

[@coffeemaplays4787]

Pratiksha Same here :(

[@pratiksha8150]

@Esther23 daisy :I'd suggest that you try & watch the videos on a Channel by Randy Neil, MD It sure helped me out!😃

[@coffeemaplays4787]

Pratiksha Thank u so much :)

[@DirtyMedicine]

Per our student polls, it shows up less than 4% of the time. If you are pressed for time, it's simply not worth the brain space. If you have time, then sure learn it

[@liebedich2441]

Pratiksha how did u apply for it can u suggest nything about applying to USMLE procedure?

[@veetown9036]

Case control studies can be both retrospective and prospective actually

[@alfreddedrummer1381]

Isn't it that Cohort study can be both whilst case control study can only be retrospective since we have the condition of interest...?

The fact that everything even remotely math-related has to be taught in medicine at such a baby-level is a sobering testimony that doctors are not exactly the brightest bunch out there.

[@StinaDeL]

you must not be a doctor if you have the ability to generalize like this. There is an abundance of medically applicable information to retain, so sometimes its nice to have an easy to follow video regarding small details in biostats.

[@lm58142]

@@StinaDeL Yes, I do have the ability to generalise. Don't you? And yes, I am a doctor despite you not letting me be one.
