Kaplan–Meier (K–M) survival analysis and ROC analysis of lncRNA signatures from TCGA OSCC dataset. A The K–M survival curve showed that low LINC02147 expression resulted in worse overall survival (OS) in OSCC patients. B The K–M survival curve showed that high expression of RP11-108K3.1 resulted in worse OS in OSCC patients. C The K–M survival curve showed that low expression of LINC01725 resulted in worse OS in OSCC patients. D–F Validation of LINC02147, RP11-108K3.1, and LINC01725 expression in TCGA. G The ROC curve showed the AUC of LINC02147 was 0.893. H The ROC curve showed the AUC of RP11-108K3.1 was 0.890. I The ROC curve showed the AUC of LINC01725 was 0.640. J–L Comparison of expression levels for LINC02147, RP-108K3.1, and LINC01725 in OSCC of different TNM stages. Global differences in survival curves were compared by log-rank test. Expression differences in OSCC and normal tissues were compared by the Wilcoxon test. Expression differences in OSCC of different TNM stages were compared by the Kruskal–Wallis test
