We identified women with hypertensive disease from the Perinatal Registry, and distinguished the period before, during and after the trial. We included 43 641 women. Induction of labour increased from 58.3 to 67.1% (P < 0.001) and prevalence of eclampsia decreased from 0.85 to 0.19% (P < 0.001) before and after the trial. Concurrently, participation in the HYPITAT trial among others had immediate consequences for obstetric management and maternal health.en© 2011 The AuthorsEclampsia; hypertension; induction of labour; preeclampsia; pregnancyJournal article002013680210.1111/j.1471-0528.2011.03138.x0002971023000142-s2.0-8125513701215354Mol, B.
