Sensitivity, Specificity, Screening Tests & Confirmatory Tests

[@Shalalashaska]

I can't thank you enough for making all these videos. Straight to the point and well explained. I hope you become a very successful physician and a happy life.

[@jennakhivkapratt8751]

Thank you! Can't ever remember the difference between the two and your gun analogy really helped and the C for confirmatory and S for screening solidified understanding of clinical application. (Taking my APRN boards this week)

[@veranice30]

Please continue your work. It is very straightforward and easy to understand. Thank you (I'm in Biostatistics/Epidemiology for Master's in Nursing)

i have no money .......so i am very happy u have topics that i can understand better fo step one

[@jmcpherson25]

i watched ur hypersensitivity video and i thank god for u. im in nursing school and it helped me understand it so much best ever video. will u ever post more videos on other disease processes?

[@stomponstep1989]

+jade m Thank you so much for the kind words :) I plan on posting videos covering pretty much everything I learned in medical school, but it will unfortunately take me a LONG time to accomplish that goal. I'm still a full time medical student (and part time masters in public health student) so I don't have a ton of free time and each videos usually takes dozens of hours of work from start to finish. But keep an eye out for more videos as I hope to release a few videos every month or so.

really helpful. i never understand spin in spin out. S=screen C=confirm is the best way to remember. also last part of the example is really useful for application when to select......Thanks

[@Shelou2006]

Happy I stumbled upon this, very helpful :-)

Validity of diagnostic test

[@MegaKaylicious]

I thought ROC curves was high yield??

[@stomponstep1989]

MegaKaylicious Understanding the ROC curve may help you understand other highyield topics but I think the odds of you being given an ROC curve on your Step 1 exam is very low. My high yield rating is mostly based on the frequency of occurrence in a giant sample of practice questions (>5000) that includes commercially available practice questions and retired Step 1 questions (AKA the NBME Self Assessments). Out of that huge sample of questions there is not a single ROC curve and I didn’t have one when I took the real exam. You can learn more about my high yield rating here www.stomponstep1.com/high-yield-rating-hyr/ That being said ROC curves are listed on the USMLE content outline so it is still possible you will get one

[@abrahamcho85]

Stomp On Step 1 hey do you have a list of topics that you rated high yield?? ... great videos by the way !!

[@stomponstep1989]

Abraham Cho Here is the biostats list www.stomponstep1.com/high-yield-rating-list-for-biostatistics-and-epidemiology/ & here is Biochem www.stomponstep1.com/usmle-biochemistry-high-yield-rating-biochem-for-step-1/ I unfortunately haven't had a chance to make a list for the other chapters yet. Hope to have those soon

[@stomponstep1989]

[@abrahamcho85]

wow this is amazing !! thanx so much... your videos are great ...going to finish up the biostats tonight

[@ManyxSurgery]

You got the equation wrong: sensitivity= TP/(TP+FP)!, but really good otherwise

[@goodman5836]

no he didn't bro

[@samerdahhan]

Despicable mo No, you are wrong
