hi. i am doing a systematic review and meta-analysis. the studies included are two-group pre-post quasi-experimental. all the studies have ONLY reported the pre-post test mean and SD. is it possible to draw a forest plot with only mean and SD? Please help.
Hi Monalisa,
Sure you can draw a forest plot as long as you're doing a meta analysis. Because it shows you the result estimated from the studies you're including. But you need to calculate the standard error for each study. I recommend you to use a simple software "MetaXl" that was developed by @Suhail A. Doi et al. You can download it from the following link:

In order to do meta-analysis and draw a forest plot, you need the sample size form each study so that you can calculate the standard errors.
Mean can be used as effect size... We need standard error...
You can use the trial version of Medcalc and it's easy and awesome...
