BRD2 and Infertility: Table 2 presents the baseline characteristics of the study groups both before and after propensity score matching (PSM). Initially, we identified 270 women who had experienced live birth and 744 women who had experienced non-live birth. Before PSM, significant differences between the groups were observed in maternal age (p < 0.001), duration of infertility (p = 0.045), AMH levels (p < 0.001), basal FSH levels (p = 0.018), and endometrial thickness on the day of embryo transfer (p = 0.005).
