How to compose easily two ORs and CI95% I need to compose ORs and CIs. I have an OR/CI95% for treatment A vs treatment B and an OR/CI95% for treatment B vs treatment C, and I want to get the OR of treatment A vs treatment C with the CI95.
It seems I can multiply ORs and CIs, but I should get a CI99.7%. How can I get the CI95 in cargo cult mode ?
Thanks !

It seems challenging with the information you have. You should be able to compute the OR of treatment A vs treatment C but you need for information for computing the CI. Here are some resources that you might find useful: https://www.ncbi.nlm.nih.gov/books/NBK431098/
