GAD: Gestational age at delivery, ACA: acute chorioamnionitis, MVU: maternal vascular underperfusion, FVTOD: fetal vascular thrombo-occlusive disease, CPI: chronic placental inflammation.

Adjustment for ethnicity, maternal age, parity, gestational age at delivery, fetal sex, and chronic placental inflammation was based on a multiple logistic regression model.
b
Without adjustment for gestational age at delivery.
