Assessment of the prognostic value of the signature in the training cohort, test cohort, and TCGA-LUSC cohort. A-C Kaplan–Meier (K-M) analysis and D-F Time-dependent ROC curves to compare the survival of high-risk group and low-risk group. G-I Heatmap for expression levels of 5 PRlncRNAs involved in the signature. J-L Risk curve for risk scores and M-O Scatterplot for the survival status of each patient
