The Limit of Viability -- Neonatal Outcome of Infants Born at 22 to 25 Weeks' Gestation

Abstract
With improved survival of preterm infants, questions have been raised about the limit of viability. To provide better information and counseling for parents of infants about to be delivered after 22 to 25 weeks' gestation, we evaluated the mortality and neonatal morbidity of preterm infants born at these gestational ages.
