| Length of stay in hospital, days | 6.0 (3.0–14.0) | 4.0 (2.0–7.0) | <0.001 |
| Plasma glucose on admission, mmol/L | 6.8 (6.0–9.4) | 6.6 (5.5–8.6) | 0.030 |
| Creatinine, μmol/L | 95.0 (66.0–137.8) | 82.0 (65.0–108.0) | 0.002 |
| Urea, mmol/L | 9.1 (6.7–16.0) | 6.7 (5.0–9.8) | <0.001 |
| Estimated GFR, mL/min/1.73 m2 | 63.0 (37.0–93.5) | 78.0 (54.0–101.0) | <0.001 |
| Sodium, mmol/L | 137.0 (133.0–140.0) | 139.0 (136.0–141.0) | 0.001 |
IQR = interquartile range; GFR = glomerular filtration rate.
