Construction of the prognostic nomogram. A Venn diagram showing the intersection between the differentially expressed ubiquitination-related genes and the 22 ubiquitination-related genes. B Heat map showing the differential expression of the intersecting genes. C Forest plot of the univariate Cox regression analysis data of the intersecting genes. The P values, hazard ratios, and associated 95% confidence intervals are shown in the figure. Red and blue represent risk and protective genes, respectively. D Prognostic nomogram. Each patient’s value is located on each variable axis, and a vertical upward line determines the number of points received for each variable value; the sum of these values is located on the “total points” axis, and a vertical downward line determines the likelihood of a 3- or 5-year survival. E Multi-index ROC curve for the nomogram. Red and blue represent the 3- and 5-year survival, respectively. The AUCs for the 3- and 5-year survival were 0.722 and 0.786, respectively
