  1. Analyses were performed after adjustment for age, infertility duration, gravidity, parity, main cause of infertility, number of OPU prior to FET, year of treatment, and number of embryos transferred, and embryo developmental stage at transfer
  2. AOR adjusted odd ratio; FET frozen-thawed embryo transfer; OR odd ratio; PCOS polycystic ovary syndrome. Implantation rate was defined as the number of gestational sacs visualized on ultrasound examination divided by the number of embryos transferred. Ongoing pregnancy rate was defined as a viable pregnancy that progressed beyond 12 weeks of gestational divided by the number of embryos transferred for each group. Live birth rate was defined as the number of live births divided by the number of embryos transfer for each group
