Table 4.
Survival of patients in different stages, according to the different staging systems: CLIP, Okuda, and Child-Pugh classifications (n=257 patients)
| Classification system | No (%) | Median (95% CI) survival (months)* | One year survival (%) | Three year survival (%) | Five year survival (%) |
| CLIP | |||||
| 0 | 62 (24.1) | — | 92 | 67 | 67 |
| 1 | 65 (25.3) | 32.6 (19–46) | 80 | 37 | 17 |
| 2 | 48 (18.7) | 12.7 (9–17) | 52 | 20 | 0 |

| Child-Pugh | |||||
| A | 191 (74.3) | 27.9 (19–37) | 67 | 38 | 29 |
| B | 49 (19.1) | 8.5 (4–13) | 37 | 5 | 0 |
| C | 17 (6.6) | 3.5 (0–7.7) | 18 | 0 | 0 |
*Median survival could not be calculated for the CLIP stage 0 as the last cumulative survival in this group was 67%. Median survival is the first observed time when cumulative survival is 50% or less.
