  1. Women without PE was the reference group. OR, odds ratio; 95% CI, 95% confidence interval. Model 1: Unadjusted, Model 2: Adjusted by systolic and diastolic blood pressure (office hypertension by systolic and diastolic ABPM, ABPM hypertension by office BP, daytime hypertension by nocturnal BP, and nocturnal hypertension by daytime BP). Model 3: Model 2 plus maternal age, gestational age at blood pressure measurements, diabetes mellitus, chronic hypertension and treatments with antihypertensives, low doses aspirin and calcium supplements. Goodness-of-fit of the fully adjusted model:
  2. aPearson 0.98 Deviance 1.00
  3. bPearson 0.96 Deviance 1.00
  4. cPearson 0.99 Deviance 1.00. No multicollinearity was observed: VIF < 5 in all Models
