Abbreviations: CI, confidence interval; Ghtn: gestational hypertension; PTB: preterm birth.

Note: The postscreen cohort 124 had delivery data available and in the prescreen cohort 139 had delivery data available. OR adjusted for baseline characteristics in ►Table 1 using multivariable logistic regression analysis with backward selection.

Indicates significance, p < 0.05.
