Establishing prognostic models for intrahepatic cholangiocarcinoma based on immune cells

Figure 3 Establishing a 3-year Cox proportional hazards prognosis model using stepwise selection and Cox multivariate regression. A: 3-year prognosis model nomogram established through multivariate Cox regression using variables from model selection of the 3-year prognostic model; B: Kaplan-Meier analysis of the 3-year prognosis model indicates a significant decrease in prognosis in high-risk vs low-risk individuals within 3 years (P < 0.001). N: No; Y: Yes; 0: No necrosis; 0.5: Partial necrosis; 1: Large or complete necrosis.
