  1. The D3-statistic is a pooled likelihood ratio test statistic across multiple imputations
  2. Model 1: Unadjusted model
  3. Model 2: Adjusted for maternal age, pre-pregnancy BMI, parity, ART, family history of hypertension, smoking status, alcohol intake, HbA1c level before 20 weeks of gestation, season of EDC, infant sex, and gestational age when BP was measured
  4. 1 s.d. = 10 mmHg for office SBP, 8 mmHg for office DBP, and 8 mmHg for office MAP
  5. 1 s.d. = 9 mmHg for home SBP, 7 mmHg for home DBP, and 7 mmHg for home MAP
  6. ART assisted reproductive technology, BP blood pressure, BMI body mass index, DBP diastolic BP, EDC estimated date of confinement, HBP home BP, MAP mean arterial pressure, OBP office BP, PMPCs placenta-mediated pregnancy complications, SBP systolic BP, s.d. standard deviation
