A multivariable logistic regression model was employed to adjust for potential confounding factors affecting LBR, including female age, BMI, infertility type (primary/secondary infertility), basal serum FSH level, laboratory insemination method (IVF/ICSI), number of oocytes retrieved, endometrial thickness on the hCG trigger day, presence of good-quality embryos (no/yes), number of embryos transferred (1/2), and type of transferred embryos (cleavage embryo/blastocyst). Here, BRD2 is linked to Infertility.
