Table 1 presents the baseline characteristics. No difference was observed in maternal BMI, gravidity, infertility cause, and endometrial thickness between the two groups. Maternal age, parity, basal FSH level, endometrial preparation protocols, and fertilization method showed significant differences between the two groups (P<0.05). These parameters were then adjusted as potential confounders in the logistic regression (Table 3) and multiple linear regression analyses (Table 4). Here, BRD2 is linked to Infertility.
