Development of a nomogram for predicting liver transplantation prognosis in hepatocellular carcinoma

Figure 1 Selection of the variables of random forest model and the time dependence area under the curve of the models. A: Number of best trees and variable importance plots obtained from the random forest method for overall survival (OS); B: Number of best trees and variable importance plots obtained from the random forest method for recurrence free survival (RFS); C: The area under the curve (AUC) of 1, 3, and 5 years of the cox model for OS; D: The AUC of 1, 3, and 5 years of the cox model for RFS; E: The AUC of 1, 3, and 5 years of the forest model for OS; F: The AUC of 1, 3, and 5 years of the forest model for RFS. AFP: Alpha-fetoprotein; TTD: Total tumor diameter; VI: Vascular invasion; CK18: Cytokeratin-18; MTD: Maximum tumor diameter; DCP: Des-gamma-carboxy prothrombin; MI: Membrane invasion; GP73: Golgi protein 73; ML: Microsatellite lesions; AUC: Area under the curve.
