Figure 2From: 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-analysisTotal gonadotrophin dose. Total gonadotrophins dose for hMG versus r-hFSH in 14 studies (data reported by study authors for 3272 patients). Forest tree with mean difference using the random effects model. Results from Balasch, Kilani and Duijkers are not included, since a fixed dose was used in their studies [24, 25, 46]. hMG = human menopausal gonadotrophins; r-hFSH = recombinant human follicle-stimulating hormone; EISG = The European and Israeli Study Group; CI = confidence intervalBack to article page
