Hi I am currently doing a systematic review and meta analysis comparing 3 PDE5 inhibitors for the treatment of erectile dysfunction, the studies are alll interventio vs placebo, however some
are flexible dosage and some are fixed dosage, how would I incorporate these dosages in a forest plot? Would I pool them all together? Or have two seperate forest plots, one competing fixed dosage and one comparing flexible dosage? Also I second question is would a traditional meta analysis or a network meta analysis Work best for my review? Bare in mind all trails compare against placebo
thanks
