Table 3.
Comparisons of the value of three models in predicting prognosis of overall survival among the patients in derivation and validation cohort.
| Models | C-index | 95% CI | P-value | AIC |
|---|---|---|---|---|
| Derivation cohort | ||||
| Child–Pugh score | 0.528 | 0.504–0.553 | Ref | 3034.66 |
| ALBI grade | 0.559 | 0.532–0.586 | 0.023 | 3023.84 |
| AAPR grade | 0.601 | 0.570–0.632 | < 0.001 | 3007.73 |
| Validation cohort | ||||
| Child–Pugh score | 0.533 | 0.489–0.705 | Ref | 710.09 |
| ALBI grade | 0.585 | 0.531–0.639 | 0.039 | 702.20 |
| AAPR grade | 0.600 | 0.545–0.655 | 0.012 | 700.61 |
ALBI, albumin–bilirubin; AAPR, albumin-to-alkaline phosphatase ratio; CI, confidence interval; Ref, reference; AIC, Akaike information criterion. A lower AIC, indicating lower loss of information, was more representative of the model.
