Figure. Association of Maternal Diabetes and Adverse Neonatal Outcomes After Very Preterm Birth.

Severe neonatal morbidity was indicated by an intraventricular hemorrhage (IVH) grade of 3 to 4, cystic periventricular leukomalacia (cPVL), and severe retinopathy of prematurity (ROP) that needed treatment or bronchopulmonary dysplasia (BPD). Propensity score–matched odds ratios were stratified by network. The infants were very preterm infants (<32 weeks of gestation) and were considered very low birth weight (<1500 g). NEC indicates necrotizing enterocolitis; PDA, patent ductus arteriosus; RDS, respiratory distress syndrome.
