Continuous positive airway pressure (CPAP) vs supplemental oxygen

Bronchopulmonary dysplasia at 28 days · preterm infants with respiratory distress for initial respiratory support

It is very uncertain whether CPAP changes bronchopulmonary dysplasia (oxygen dependency at 28 days) compared with supplemental oxygen (very low certainty).
