Associations between moderately-elevated blood pressure during pregnancy, stratified by placental/placental membrane findings, and maternal blood pressure at follow-up (7–15 years after POUCH Study pregnancy) among women with no hypertensive disorders during the POUCH Study pregnancy (N=450)

Blood Pressure (BP)at follow-up (n=450)

	<130 Systolic BP and <80 Diastolic BP	130–139 Systolic BP and /or 80–89 Diastolic BP			≥ 140 Systolic BP and /or ≥ 90 Diastolic BP or currently taking medications
