Diskussion & Kritik
The benefit is confined to preterm pre-eclampsia — term disease and hard perinatal outcomes were not significantly reduced — and the trial rests on few events. It established both the effective dose (150 mg, higher than the 75–81 mg used before) and the value of algorithm-based first-trimester screening.
