AGA and bronchopulmonary dysplasia: Univariate analysis performed to evaluate potential predictors and risk factors associated with BPD revealed that AGA (unadjusted OR 2.07, 95%CI 1.34-3.19, P = 0.001), intubation (unadjusted OR 7.23, 95%CI 5.66-9.22, P < 0.001), surfactant administration (unadjusted OR 5.48, 95%CI 4.27-7.03, P < 0.001) during resuscitation, use of inhaled nitric oxide (unadjusted OR 6.04; 95%CI 3.61-10.11; P < 0.001), and invasive ventilation (unadjusted OR 8.05, 95%CI 6.29-10.31, P < 0.001) were significantly associated with a higher risk of developing BPD.
