BRD2 and polycystic ovary syndrome: Table 1 lists the baseline characteristics pre- and post-PSM. Prior to PSM, patients with PCOS were younger (29 vs. 31 years; p < 0.001), had a higher BMI (23.95 vs. 22.2 kg/m2; p <0.001) and basal LH level (8.49 vs. 4.38 mIU/ml; p < 0.001), and had a lower level of basal FSH (5.73 vs. 6.10 mIU/ml; p <0.001), than did those in the control group. Furthermore, there was a significant between-group difference in infertility type (p =0.003).
