Such a determination generally cannot be made, given a lack of supplemental exposure data in NHANES.
For infants treated in the neonatal intensive care unit, we created an oxygen exposure variable: no supplemental oxygen exposure during the neonatal period, no bronchopulmonary dysplasia (BPD); supplemental oxygen exposure of 1 to <200 hours during the neonatal period, no BPD; supplemental exposure ≥200 hours during the neonatal period, no BPD; and BPD.

Neither degree of ventilatory support nor supplemental oxygen exposure correlated with surfactant metabolic indices.
Supplemental oxygen exposure, while a risk factor, is not the main risk factor for development of this disease.
We classified infants who did not require intensive care during the neonatal period as having no supplemental oxygen exposure.
12– 14 An artefactual increase in SpO2 from 89% to 91% would result in fewer infants being categorised as having bronchopulmonary dysplasia and might influence the duration of supplemental oxygen exposure.
To assess the prognostic accuracy of early cumulative supplemental oxygen (CSO) exposure for prediction of bronchopulmonary dysplasia (BPD) or death, and to evaluate the independent association of CSO with BPD or death.
