I take Step 2 this week and I think I just learned more biostats in 26 minutes than I did in 3 months worth of Uworld problems. Not all heroes wear capes. 💥

the person who gave you a thumbs down is probably mad cause they didnt find this video before their test

Every single video is a gift, literally! Thank you Dr. Neil. I'm always excited to get notifications from your channel!

Before watching Dr Neil's videos I felt like an absolute mess when faced with a Biostats Q and now it seems too easy it's unbelievable! My only regret is that I didn't find these videos earlier as my Step 3 is 1 week from today but even so they were more helpful than a whole 2 weeks of studying Biostats so thank you so much Dr Neil and God Bless you! I am literally going to recommend this channel to everyone I know! Good luck everyone 🙏

The genius of your videos is that they offer something very different. Its very hard to establish yourself nowadays teaching on the Internet. The competition is simply not fair. Your videos however target a part of the material that most larger comapnies don't cover too well (not in a practical way at least).
Very grateful for your work. My CK is tomorrow 🙏🙏

In last question about the Odss Ratio, the answer should be (60/200)/ (40/160), why is it option C?

And in the question about the RR about the prostate cancer
The formula you wrote is (a/a+b)/ (c/c+d) 15:43 and because "first on top" it goes backwards, (c/c+d)/(a/a+b), but still, the process you followed was (b/b+d)/ (a/a+c)... im confused

You are always so calm. I am going through your videos and noticing how peaceful he seems❤❤

[michaeldasso]

For the Odds Ratio question, I believe the answer should be (60/40)/(200/160).
Odds Ratios (a/c)/(b/d) represent the odds of exposure among cases (a/c) vs odds of exposure among controls (b/d). In this problem, being old is represented as the exposure (a, b) and the case is represented as a low score (c, d).

Never seen such a simplified and comprehensive lecture of biostat.

Preparing for anesthesiology boards, going back to your videos to review the basics of biostats! Your videos are gold!!

Taking STEP tomorrow morning, so grateful for this video!

[DrAsadN]

Watching this 2 hours before step 1. You’re the goat Dr. Neil 💪🏻

[abdallahjlambo]

When I watched you are videos the first idea pop into my head was (Please, we need more and more) do not hold back these informative quick reviews.

[shisuiuchiha-hh]

once again i'm here for the biostats teacher ever for my step 2 CK. done with step1, highly recomment Randy Neil, MD. i literally can't stress it enough how important it is to watch and understand his videos.

[walkaboutinside]

I am a Psychiatry trainee and I have to say your explanation and drawings are spot on. Kudos to you.

[SN-qtzk]

Your biostats videos are literally a godsend. I can't thank you enough.

[asivz]

i remember watching the original vids a few years ago and thinking you were an attending. wild that you were just beginning residency at the time; so impressive! thanks for all the hard work you do!

[MaryloP.B]

Mille merci Dr Neil ! Thank you so much! I really struggled with biostats, your teaching skills made it so easy to look at these questions with a calm mind and more confidence!

[ceph-azolin]

I am an IMG, the first thing I am gonna do is to meet you and appreciate your work. GOVERNOR OF BIOSTATS

Thank you for your help Dr Neil! Just one question. On 22:10 you said it is a case control study. I think it is a retrospective cohort since we can look at low USMLE scores as a disease. So if we have two groups, one with a risk factor for low score (being older) and one without the risk (being younger) and we look retrospectively to see if they had low scores ('a disease') then I would consider it a cohort study. It is similar to observing if smokers and non-smokers developed COPD or SCLC. If it was a case control, we would have a group with low scores (a disease) and a group without low scores (no disease) and then we would look if they were exposed to a risk factor such as an old age. Please correct me if I'm wrong.
