ANCOVA analysis to investigate the association between global placental DNA methylation (dependent variable) and birth weight for gestational age (aAGA was used as a reference); SGA = small for gestational age; AGA = appropriate for gestational age; LGA = large for gestational age; BMI = body mass index; SBP = systolic blood pressure;.
