Model I: Age, ethnicity, education, blood type, BMI
Model II: ModelI + IVF, gestational age, Parity, Number of Births, GWG, HDP, GDM, ICP, hypothyroidism during pregnancy, anaemia during pregnancy, delivery mode
Model III: Model II + BW, sex of the newborn
The A/G ratio was analyzed as a continuous variable, with effect sizes expressed per 0.1-unit increase. The A/G ratio was categorized into two groups with cut-off points at 1.29 and three groups (G1, G2, and G3) with cut-off points at 1.15 and 1.40. G1: A/G < 1.15; G2: 1.15 ≤ A/G ≤ 1.40; G3: A/G > 1.40
