NAMPT and bronchopulmonary dysplasia: VLBW neonates developing BPD (n = 18) exhibited lower gestational age and birthweights (Table 2) and significantly increased NAMPT expression compared to non-BPD neonates (n = 18) (Figure 1H) yielding an area under the receiver operating characteristic curve of 72.3% in predicting BPD at 4 weeks of age (Figure 1I).
