title: Preterm mortality and morbidity over 25 years.
abstract: Changing preterm population variables have masked improvements in neonatal survival over time. Increased use of antenatal steroids, caesarean section, and surfactant may have reduced the likelihood of mortality and periventricular haemorrhage by a third and doubled that of chronic lung disease, persistent duct, and septicaemia.
