Establishment and validation of an intratumoral fibrosis-based nomogram for predicting aggressive recurrence after liver resection in hepatocellular carcinoma

Figure 6 Performance evaluation of the predictive nomogram. A: Time-dependent receiver operating characteristic curve for 1-year and 2-year aggressive recurrence in the training cohort; B: Time-dependent receiver operating characteristic curve for 1-year and 2-year aggressive recurrence in the validation cohort; C: Calibration plot comparing predicted vs observed probabilities at 1 year and 2 years in the training cohort; D: Calibration plot at 1 year and 2 years in the validation cohort; E: The 1-year and 2-year decision curve analysis curves of the training cohort; F: The 1-year and 2-year decision curve analysis curves of the validation cohort. AUC: Area under the curve.
