Figure 8 Nomogram construction and validation for the six-gene risk score in The Cancer Genome Atlas liver hepatocellular carcinoma. A: Single multivariable Cox nomogram integrating risk score, age, sex, pathological stage, and tumor grade, with separate scales for 1-, 3-, and 5-year overall survival probabilities; B-D: Bootstrap calibration curves for 1-, 3-, and 5-year overall survival prediction; E-G: Decision curve analyses at 1, 3, and 5 years; H: Harrell’s C-index for the risk score-only and combined models in the training and internal validation cohorts.
