Univariate and multivariate Cox regression analyses for risk score and construction of a nomogram. (A, B) Univariate Cox regression and multivariate Cox regression analyses of five PRGs and clinical features. (C) A nomogram containing the prognostic signature and different clinicopathological parameters was constructed. (D) Calibration curve of the actual 1-, 3-, and 5-year OS. (E) Association between the risk score and the infiltration abundances of six immune cells. (F) Heatmap depicting the correlations between the risk score and five PRGs and the infiltrated abundances of six types of immune cells. *p < 0.05, **p < 0.01.
