Figure 7. Prognostic value of the riskScore gene signature. (A) Forest plot showing the riskScore was an independent prognostic biomarker using multivariate analyses. (B) The nomogram was constructed to predict the probability of patient mortality. (C) The Predictive efficacy of nomogram score on prognosis. (D) The calibration plot of nomograms between predicted and observed 3-year and 5-year outcomes. The 45-degree line represented the ideal prediction. (E) The GSEA enrichment reveals two significantly activated signaling pathways, including the cell cycle pathway.
