Hi all,

I am conducting a systematic review and meta analysis that will investigate health-related quality of life in a particular patient population. I am encountering difficulties as the results obtained from the included studies do not have a control group. I only have the mean and standard deviation for the patient population. It seems that the metan function requires two groups, an experimental group and a control group. Any help or advice would be greatly appreciated. (I am still very new to Stata so the simpler the better!)

Thank you.
