Figure 3From: Recombinant human follicle-stimulating hormone produces more oocytes with a lower total dose per cycle in assisted reproductive technologies compared with highly purified human menopausal gonadotrophin: a meta-analysisPregnancy rate. Pregnancy rate for hMG versus r-hFSH in 16 studies (main analysis population, data reported by study authors for 4040 patients). Forest tree with random model and relative risk. hMG = human menopausal gonadotrophins; r-hFSH = recombinant human follicle-stimulating hormone; EISG = The European and Israeli Study Group; CI = confidence intervalBack to article page
