I have a bunch of articles presenting “OR” with a- 95% CI (confidence intervals).
I want to estimate from the articles the P value for the observed OR. For that, I need an assumption regarding the OR distribution. What distribution can I safely assume/use?
Answer
The log odds ratio has a Normal asymptotic distribution :
log(^OR)∼N(log(OR),σ2log(OR))
with σ estimated from the contingency table. See, for example, page 6 of the notes:
