In neonates with no PDA the odds of BPD or death was almost doubled for every one unit increase in the natural logarithm of the concentration of NT-proBNP when adjusted for GA (OR = 1.9; 95% CI: 1.1; 3.2) and increased by 4-fold in neonates with a clinically significant PDA (OR = 4.4; 95% CI: 1.3; 16), whereas no statistically significant association was found in neonates with a non-clinically significant PDA (OR = 1.2; 95% CI: 0.6; 2.4). Here, NPPB is linked to Patent ductus arteriosus.
