Hi steve, thanks for the reply. The sas code you saw there was gotten from the internet. I not really sure of it's correctness. I have been instructed to carry out a full meta-analysis of a normally distributed data on sas, as well as to produce the forest plot(95% CI). Ordinarily, the CMA package is what I'm used to but the instruction was that i should use sas for the analysis. The data is of the form; trial mean_of_new_treat stand_dev_of_new_treat numb_on_new_treat mean_of_placebo stand_dev_of_placebo numb_on_placebo 1 5.7 6.2 12 5.2 6.3 10 2 6.3 5.6 120 7.5 6.2 122 3 6.9 4.5 63 7.1 4.3 64 4 7.3 5.4 58 7.5 3.4 56 Thanks ib
