Decision curve analysis of the nomogram. DCA graphically illustrating the clinical utility of the nomogram model. The x-axis represents threshold probability and the y-axis represents net benefit. The gray lines indicate that all patients are assumed to have postoperative recurrence, and the black lines indicate that no patient is assumed to have postoperative recurrence. With a broad range for predicting postoperative recurrence, the nomogram has greater net benefit than the conventional staging systems and treat-all or treat-none strategies for patients with HCC. DCA, decision curve analysis; RFS, recurrence-free survival; TNM, tumor-node-metastasis staging system; CLIP, Cancer of the Liver Italian Program score; BCLC, Barcelona Clinic Liver Cancer staging system.
