| Urinary albumin (mg/l) | 29 (24; 36) | 62 (51; 77)* | 56 (41; 76)* | 67 (51; 90)* |
| FENa (%) | 2.6 (2.3; 2.9) | 3.6 (3.2; 4.2)* | 3.8 (3.0; 4.8)* | 3.6 (3.0; 4.2)* |

NGAL urine neutrophil gelatinase-associated lipocalin, SCr serum creatinine, AKI acute kidney injury, FENa fractional excretion of sodium, PDA diameter <1.5 mm small PDA, PDA diameter ≥1.5 mm large PDA. Values are geometric mean (95% confidence interval) or number (percentage). *p < 0.05 compared to neonates with no PDA. U-NGAL day 6 was only measured in 126 neonates
