An update on the impact of postnatal systemic corticosteroids on mortality and cerebral palsy in preterm infants: effect modification by risk of bronchopulmonary dysplasia.

Infants at higher risk of bronchopulmonary dysplasia had increased rates of survival free of cerebral palsy after postnatal corticosteroid treatment in a previous metaregression of data from 14 randomized controlled trials. The relationship persists and is stronger in an updated analysis with data from 20 randomized controlled trials.
