Oh yeh should've used the hashtag lol
I have noticed many studies are reporting OR much more than RR in epi studies I’ve been reading lately. (Some HR, but mostly OR lately.) I’m not sure why. Maybe the higher number is more impressive for publication (part of publication bias)?
My bet is that it's because everyone dichotomizes their outcomes and uses logistic regression
Great stuff @GidMK
Why do some cohort studies use OR instead of RR - is that because some use logistic regressions?
It depends, but often yes
Thanks for this. _Never_ had the difference explained to me and certainly never actually knew how an odds ratio was derived. Rather embarrassing as one of the EBM faculty. But also distressing as I’ll give you good odds that nearly all of my colleagues don’t understand either.
