[R-meta] Calculating odds ratios in bivariate meta-analysis.

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

Regards
