| Factor | Alive (n = 87) | Dead (n = 153) | p value |
| Median age (IQR; years) | 62.5 (48–72) | 71 (59–79) | <0.0001 |
| Mean Charlson co-morbidity index score (±SD) | 5.3 (± 3.6) | 6.7 (± 3.5) | 0.002 |
| Mean APACHE II score (± SD) | 30.3 (± 8.5) | 34.8 (± 8.3) | 0.0001 |
| Median pre-dialysis creatinine (μmol/l) (IQR) | 470 (341–582) | 344 (250–475) | 0.0001 |
| Median pre-dialysis platelets (×109/l; IQR) | 156 (71–241) | 83 (41–170) | 0.0001 |
