Establishing prognostic models for intrahepatic cholangiocarcinoma based on immune cells

Figure 2 Establishing a 1-year Cox proportional hazards prognosis model for intrahepatic cholangiocarcinoma using stepwise selection and Cox multivariate regression. A: 1-year prognosis model nomogram established through multivariate COX regression using variables from stepwise selection of the 1-year prognostic model; B: Kaplan-Meier analysis of the 1-year prognosis model indicates a significant worsening in prognosis for high-risk vs low-risk individuals within 1 year (P < 0.001).
