Nomogram to predict OS of patients with hepatic metastatic GEP-NETs. To validate the nomogram, the sum of each predictor point was charted on the total points axis. The estimated 1-, 2-, and 3-year OS rates were estimated by plotting a straight vertical line from the charted total points axis to the same OS rate axis. For the “number” line, 1 indicates a single hepatic lesion and 2 indicates multiple hepatic lesions. For the “treatment” line, 1, 2, and 3 refer to local treatment, combined treatment, and systematic treatment, respectively. For the elevation line, 0 indicates no elevation of the Ki-67 index
