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.

Not sure where exactly the problem is, but escalc() with measure="OR"
computes log odds ratios and measure="PLO" computes log odds.
