Distribution of mean, standard deviation (SD), median, and ranges of vascular density (VD) and H-ras expression in normal livers (group I), nonfibrotic (group II), fibrotic (group III), and cirrhotic livers (group IV). The Mann-Whitney U test was used.
| Group | VD | H-ras (%) | ||||||

| I (n = 6) | 3.1 ± 0.95 | 3 | 0–7 | >0.05 | 0.66 ± 0.58 | 0 | 0–4 | >0.05 |
| II (n = 8) | 6.82 ± 2.5 | 7 | 2–11 | <0.05 | 13 ± 6.08 | 12 | 3–30 | <0.05 |
| III (n = 8) | 11.3 ± 2.4 | 10 | 9–16 | <0.05 | 19.6 ± 6.39 | 22 | 10–30 | <0.05 |
| IV (n = 8) | 15.90 ± 3.7 | 16 | 10–22 | <0.05 | 25.87 ± 7.28 | 26 | 12–30 | <0.05 |
