So the story is from a poster presentation at a conference What this means in practice: - preliminary research - not peer-reviewed - likely to change before publication - less likely to be correct
That's the thing - they report using a random effects model, but I can't replicate that in Stata. I'd probably need to see their code to get the precise effect estimate they generatedpic.twitter.com/2fH3xll8Tc

(I'm also using the DerSimonian and Laird variance estimation, but my guess is that the procedure in Stata produces very slightly different results than other statistical software)

Hmm interesting. I don't think they actually used the DL method... I calculated the standard errors by taking the natural logs ln(UL/LL) and tried to reproduce it with *metan logOR logSE, fixed eform* I got much wider interval estimates (as expected with random effects)pic.twitter.com/y7kXtgU7YU
