Biostatistics UW Questions: ARR, AR, NNH

Hey guys!
Biostatistics questions about Absolute Risk Reduction (ARR), Attributable risk (AR) and Number Needed to Harm (NNH) can be very confusing on the USMLE Step 1. In this video I'll walk you through two UWorld questions and break them down in a simple way, so keep watching!

ARR- treatment is protective, less event rate so, Ec-Et AR- treatment is harmful, more event rate so, Et-Ec Event rate= a/a+b NNT=1/ARR NNH=1/AR NNH=higer number, safer drug NNT=Lower number, safer drug

Thanks alot Dr for this useful information, can you please guide us for a quick reference to get the concepts of biostatistics. Appreciating your time and help.

[@acingmedicine]

Use First Aid biostats and NBMEs, read UWorld explanations for the biostat questions. That was enough for me
