Table 6. Likelihood ratio on entry of individual staging systems as factors in Cox regression model for the whole cohort.
Staging system | LR χ2 test | −2 log likelihood | P value |
Okuda | 363 | 12869 | <0.001 |
CLIP | 679 | 12663 | <0.001 |
BCLC | 810 | 12473 | <0.001 |
JIS | 694 | 12620 | <0.001 |
LR, likelihood ratio, P value <0.05 is significant.
