# What is the distribution of OR (odds ratio)?

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?

$\log(\hat{OR}) \sim N(\log(OR), \sigma_{\log(OR)}^2)$
with $\sigma$ estimated from the contingency table. See, for example, page 6 of the notes:
