| A total Child-Pugh score of: | |||
| 5 to 6 is considered Child-Pugh class A (well-compensated disease), | |||
| 7 to 9 is class B (significant functional compromise) | |||
| 10 to 15 is class C (decompensated disease). |
These classes correlate with one- and two-year patient survival in patients undergoing surgery: class A: 100 and 85%; class B: 80 and 60%; and class C: 45 and 35%.
