White cell and neutrophil counts and plasma creatinine in the four groups (for definition of groups see patients and methods); results are median (range)
| Group 1 | Group 2 | Group 3 | Group 4 | |
|---|---|---|---|---|
| White cell count (× 109/l) | 14.5 (7.8-43.1) | 7.9 (5.0-20.2) p = 0.004 | 7.1 (4.4-20.5) p = 0.0002 | 8.9 (5.7-10.8) p = 0.01 |
| Neutrophil count (× 109/l) | 10.1 (4.3-26.5) | 4.2 (2.1-8.7) p = 0.002 | 2.3 (1.4-10.3) p = 0.01 | 4.3 (3.7-6.6) p = 0.008 |
| Creatinine (mmol/l) | 416 (74-1046) | 55 (25-84) p = 0.0002 | 160 (46-1080) p = NS | 52 (41-69) p = 0.0014 |
