Fig 2 Hazard ratios for hypertension by severity of hypertensive disorder of pregnancy (if any) in the most recent pregnancy and time since most recent pregnancy, among women with at least one live birth or stillbirth in Denmark, 1978-2012. Hazard ratios compare rates of hypertension among women with severe pre-eclampsia (orange), moderate pre-eclampsia (green), and gestational hypertension (black) in the latest pregnancy with rates of hypertension in women whose most recent pregnancy was normotensive. Follow-up began in 1995 or three months post partum, whichever came later. Hazard ratios are adjusted for maternal age, maternal birth year, and parity (see also supplementary figure 1 for corresponding figure with hypertensive disorders of pregnancy classified by timing of delivery)
