How to include data for meta anlaysis in cases where z-scores are given for outcome variables?

22 December 2018 1 7K Report

i would like to ask while retrieving data from the research papers, what we should do with research articles where the treatment and control mean(SD) values are reported in z scores and not in actual group mean(SD) scores for the outcome variables. Whether we should exclude such studies from our meta analysis or there is some way to include them? Kindly advice.
