Use of different outputs in a meta-analysis?

#1
I'm interested in performing a meta-analysis of instrumental variable analyses from a handful of different studies, asking for the same set of model results from all study investigators. As my access is limited to summarized data, i'd like the study investigators to send their ivregress output and then pool those results. However, at the moment I’m not familiar with Stata and the output ivregress generates.

Would it be possible to perform a meta-analysis using ivregress outputs from different studies?
