Discriminatory ability for death at one, three, and five years, evaluated by receiver operating characteristic (ROC) curve area, for Okuda, CLIP, and BCLC scores
| Staging system | ROC curve area | 95% CI |
|---|---|---|
| Patients censored before one, three, and five years were respectively excluded from the analysis. | ||
| Higher ROC curve area values indicate a better discriminatory ability of the score. | ||
