Hi Nigel, I'm a bit confused, at 7:16 you explain the ARC, which is the control event rate as patients who are NOT on a statin (red plus yellow faces), however yellow faces are defined as people saved from a CV because the have taken a statin. Can you please explain? thanks
How would you calculate the Number need to harm? Would that only be possible if there were the green crossed out faces? as in 100 divided by no. of green crossed out faces?
Explained it better than my pharmacy lecturers.Thank You!!
Most welcome.
This is brilliant!! thanks.
Glad you liked it!

ARR = ARC - ART, therefore ARC = ARR (yellow) +ART (red)

correct | NNH=100/ARI ( green crossed out faces)
