BRD2 and polycystic ovary syndrome: It must be remarked that differently from the previously published cost-effectiveness studies [17,18], in our study only first-treatment cycles were considered, Hp-uFSH (and not u-FSH) was used, mainly normal (and not all PCOS) patients were included, and the delivery rate (and not just the clinical pregnancy rate) was considered as the best clinical outcome indicator.
