According to the results of multivariate logistic regression analysis, which included the gestational age, for every one-unit increase in the natural logarithm of the concentration of NT-proBNP in the first 3 days of life, the odds of death or BPD increased almost 3-fold (aOR = 2.613; 95% CI: 0.901–7.578; p = 0.077), and at 8–9 days of life this increase was almost 5-fold (aOR = 4.64; 95% CI: 1.197–17.993; p = 0.026). Here, NPPB is linked to bronchopulmonary dysplasia.
