My colleague
greeting to you first of all. I am not sure exactly what is your request about metanalysis? you have here 3 groups, metanalysis may be done with 1 rarely and almost usually on 2 groups never 3 at the same time. so what is your problem exactly? I will be happy to help you as much as i can. But for sure I have to listen t your idea about your problem under study? which is the control group? which is the study group? which kind of data are you dealing with? mean and SD? or number and percent? it is vital to know those before any further help can be given and waiting for ur kind response
