(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
I got the reported results with *metan logOR logSE, fixed eform*. Double checked on R with metafor and got similar results. Any case... I don't think it actually matters whether the interval includes the null or not. All of included studies are regarding nonrandom exposurespic.twitter.com/Ng2PJYtv9A
