Adjusted Probability of Developing Bronchopulmonary Dysplasia (BPD)

Figure.

Probabilities are based on the cumulative duration of mechanical ventilation for infants exposed to 1, 2, 3, or 4 or more separate courses of mechanical ventilation and are adjusted for birth weight, gestational age, small for gestation age, sex, birth year, surfactant exposure, postnatal dexamethasone treatment, patent ductus arteriosus treatment, bacterial sepsis, and diagnosis of necrotizing enterocolitis. Plots were generated using locally weighted scatterplot smoothing (LOWESS).
