Table 3. Predictive accuracy of predictive models in terms of C‐index and AIC in overall survival and recurrence‐free survival prediction.
The larger the C‐index is, the more accurate the predictive model is, whereas for AIC, the smaller, the more accurate.
a
Corrected C‐index was generated by 10‐fold cross‐validation.
Abbreviations: AIC, Akaike information criterion; AJCC, American Joint Committee on Cancer; CI, confidence interval; C‐index, concordance index; FTS, fibrotic tumor stroma; LCSGJ, the Liver Cancer Study Group of Japan; TIL, tumor‐infiltrating lymphocyte.
