Blood chemistry and acid-base data for patients with and without hypoalbuminaemia on admission and at 24 hours
| Admission | 24 hours | |||
|---|---|---|---|---|
| Albumin <33 g/l (n=76) | Albumin ⩾33 g/l (n=58) | Albumin <33 g/l (n=101) | Albumin ⩾33 g/l (n=33) | |
| Statistical comparisons are between the low and normal albumin groups at the same time point. | ||||
| Results expressed as mean (SD). | ||||
| SB, standard bicarbonate; AG, anion gap. | ||||
