Fig. 3From: Survival analysis of patients with extrahepatic cholangiocarcinoma: a nomogram for clinical and MRI featuresThe nomogram assessing the risk probability of the ECC patient after treatment. (a) Nomogram composed of eight variables predicting 1-year and 2-year survival probability. For a given sample, each variable had a point, and the total point corresponded to the survival probability at a specific time. (b) Kaplan-Meier survival curve showing that the total point calculated from the nomogram well defined the risk levels with significantly different survival timesBack to article page
