Clinical application value of DRGPS risk score. a, b Univariate and multivariate Cox regression analyses determined the prognostic value of DRGPS risk score; c multi-ROC curves of the DRGPS risk score and other clinical factors; d a predictive nomogram predicted 1-, 3-, and 5-year OS in HCC patients; e–h calibration curve (e), clinical impact curve (f), decision curve analysis (g), concordance index (h) validated the accuracy of the nomogram. DRGPS, DRG prognostic signature; ROC, receiver operating characteristic; OS, overall survival; HCC, hepatocellular carcinoma
