Figure 2. Hazard Ratios (HRs) for Ischemic Heart Disease (IHD) and Stroke According to Preeclampsia, Preterm Birth, and Small for Gestational Age (SGA).

Offspring born to individuals without any hypertensive disorders of pregnancy were the reference, and analyses were adjusted for offspring calendar year of birth; offspring sex; and maternal parity, age, educational level, marital status, and diabetes status before childbirth. In case of IHD, the P values for interaction were P = .27 between preeclampsia and SGA and P = .31 between preeclampsia and preterm birth. In case of stroke, the P values for interaction were P = .56 between preeclampsia and SGA and P = .11 between preeclampsia and preterm birth.
