Diffuse reduction of spleen density is a novel prognostic marker for intrahepatic cholangiocarcinoma after curative resection

Figure 6 A nomogram predicts the overall survival of patients with intrahepatic cholangiocarcinoma. A: The nomogram predicted 1-, 3- and 5-year overall survival (OS) for intrahepatic cholangiocarcinoma (ICC) patients; B: The calibration plots showed excellent agreement between observed outcomes and predicted survival probabilities; C: The area under the receiver operating characteristic curve of OS. CA19-9: Carbohydrate antigen 19-9; CEA: Carcinoembryonic antigen; PCs: Postoperative complications.
