Prognostic nomogram model for overall survival in patients with hepatocellular carcinoma

Figure 4 The prediction accuracy and clinical application value of the nomogram model. A: The 1-year, 3-year, and 5-year calibration curves of the nomogram model in the training set; B: The 1-year, 3-year, and 5-year calibration curves of the nomogram model in the validation set; C: The 1-year, 3-year, and 5-year decision curve analysis curves for nomogram models in the training set; D: The 1-year, 3-year, and 5-year decision curve analysis curves for nomogram models in the validation set. OS: Overall survival; TNM: Tumor node metastasis.
