Incidence over A time and B age of gestational hypertension and pre-eclampsia amongst nulliparous women. Bars: incidence amongst nulliparous women; solid lines: incidence per 100,000 person-years; dotted lines: 95% confidence intervals. The years 1997 and 2015 were excluded from the plot as data only covered part of these years. There was less available data for 1998 and 1999 due to the parity of the pregnancies being recorded less consistently in that period
