Data are presented as percentage (n) or mean±SD. Composite fetal outcome includes preterm delivery <37 weeks, NICU admission, fetal or neonatal death, and/or small for gestational age. Outcomes are adjusted for age, race, BMI, diastolic BP at first prenatal visit, history of diabetes, and parity. P values reflect the adjusted analysis for dichotomous outcome variables, and t tests were used for continuous outcome variables. n/a, not applicable.
