(B) The forest plot illustrates the results of multivariate Cox regression analysis conducted on clinical features. (C)The nomogram of the prediction model. The segments represent the contribution of clinical factors to the outcome events, the total score represents the overall score of individual values for all variables, and the bottom three lines represent the prognosis for the 1-year, 2-year, and 3-year survival periods corresponding to each value point. (D) Calibration curves for 1-year, 2-year, and 3-year survival periods in the nomogram
