Hi, I have found different formulas for the confidence intervals. Could you share the reference from the ones you show in this video?
P.S. Thanks for your videos, they're great!

I don't remember where I first found it but you can find it, for example, here:
www.statology.org/relative-risk-confidence-interval/
I know the equations can take different forms but they should, hopefully, end up in the same CI.
