The clinical implications and prognostic role of the model. A-F Correlation between the risk score and various clinical characteristics. G Univariate Cox analysis of the risk score and clinical characteristics for OS in the TCGA cohort. H Multivariate Cox analysis of the risk score and clinical characteristics for OS in the TCGA cohort. (I) The nomogram built in combination with the risk score and the N stage predicted one-, two-, and three-year OS in the TCGA cohort. J The probabilities of OS at one-, two-, and three-year were assessed by the calibration curve of the nomogram in the TCGA cohort. * p < 0.05; ** p < 0.01; *** P < 0.001; **** P < 0.0001
