Objective To determine whether the duration of noninvasive respiratory support exposure is associated with bronchopulmonary dysplasia (BPD) or death in preterm infants. Methods Multicenter, retrospective study of infants born at Results Among 6268 infants 36% developed BPD or died. The median duration of noninvasive respiratory support was 18 days. There was inconsistency in the association between noninvasive support and BPD or death when analyzed by instrumental variable techniques (Average Marginal Effect -0.37; 95% CI -1.23 to 0.50) and generalized propensity score matching (Average Marginal Effect 0.46; 95% CI 0.33 to 0.60). Conclusion Findings on the association between duration of exposure to noninvasive respiratory support and the development of BPD or death were inconclusive.
