Honestly I was going to just say F it and not study statistics again for step 3, but this was amazing. Thank you so much for all of the work that you have put in it!!!

Hi doctor, just a question…isn’t per protocol analysis no loss to follow-up? If that’s the case, wouldn’t it be 12/20 instead of 12/13?…sorry I’m just a bit confused.

[@pranayjoshi8084]

09:35- shouldn't it be- odds of smoking were 28x greater in hypertensive patients?

[@sandhya797]

How do we explain 12/13 in ppanalysis ? In ARR
