Dear Wolfgang
Thank you for your response. I felt like the escalc() with measure
="OR" , is used for univariate meta-analysis and I thought there is
another function used to calculate odds ratios in bivariate/multivariate meta-analysis.
Regards
Olina

Dear Olina,
Not sure where exactly the problem is, but escalc() with measure="OR"
computes log odds ratios and measure="PLO" computes log odds.
Best,
Wolfgang
Hello R-sig-meta-analysis folks,
I am doing a random effects multivariate model (bivariate) for
binary outcomes, pregnancy and live birth (similar to this analysis:
https://www.metafor-project.org/doku.php/analyses:berkey1998, the
difference is that berkey1998 outcomes are continuous). Now for
bivariate analysis of binary outcomes, I want odds ratios and have
not found the way of getting log odds and odds ratio like in the
univariate analysis (for example the output for rma.peto).
Thank you
