General inverse variance method

[glassman365]

Hi

I hope I've posted this in the right place.

I'm converting standardised mean differences to log OR for a meta-analysis. Just wanting to know can I combine log OR with the standard OR I have from papers? Or would I need to convert the OR's from papers into log ORs for analysis?

Thanks. I hope I've provide enough info, and someone can help

You want them all in the same formatting (relative units).
