  1. List of variables used to adjust OR: maternal age, BMI, maternal infertility diagnosis, number of top-quality embryo transferred, occurrence of multifetal pregnancy reduction, single or multiple pregnancy, and singleton or twin delivery
  2. ICSI intracytoplasmic sperm injection, OR odds ratio, CI confidence interval, GDM gestational diabetes mellitus, LBW low birth weight, SAG small for gestation age, NICU neonatal intensive care unit, BMI body mass index
  3. Neonatal outcomes in terms of very low birth weight (VLBW) and birth defect were not analyzed by the generalized estimating equations method because a quasi-complete separation existed in the limited available data and the maximum likelihood estimates did not exist
