High tumor mutation burden indicates a poor prognosis in patients with intrahepatic cholangiocarcinoma

Figure 2 Construction of a prognostic nomogram for intrahepatic cholangiocarcinoma patients. A: The predicted 1-, 3-, and 5-year survival rates in intrahepatic cholangiocarcinoma patients based on our nomogram, which included tumor mutation burden, CA19-9, chronic viral hepatitis, tumor resection and disease progression; B: Calibration plots show that the observation and prediction results of 1-, 3-, and 5-year survival rates are consistent with the actual observation and prediction.
