Hello! I want to conduct a met-analysis using the pre-test for a treatment and a control, and the post-test of a treatment and a control after 6 weeks. I have the mean of the tests, number of participants, and SDs. When I try to use revman 5.4, I can only compare the treatment and control group without comparing pre/post. I'm not sure if this makes sense, this is my first met-analysis. What software can I use to conduct a met-analysis for pre-post results?
