Construction of Nomograms for Predicting Lung and Bone Metastases in Patients with Intrahepatic Cholangiocarcinoma and Identification of Patients Who Can Benefit from Chemotherapy

Figure 4

Classification of risk groups for the LM and BM nomograms. (a) Classification of risk groups for the LM nomogram conducted by the maximum value of the Youden index from the ROC curve and their performance in distinguishing LM. (b) Classification of risk groups for the BM nomogram conducted by the maximum value of the Youden index from the ROC curve and their performance in distinguishing BM. (c) Kaplan–Meier curves of OS for ICC patients stratified by high-risk and low-risk groups of LM; (d) Kaplan–Meier curves of OS for ICC patients stratified by high-risk and low-risk groups of BM. LM: lung metastasis; BM: bone metastasis; ROC: receiver operating characteristic; OS: overall survival; ICC: intrahepatic carcinoma.
