Construction of mRNA-miRNA. A Sankey diagram showed the association between CCR7, CCL19, miRNAs and risk type. B, C Correlation between CCR7 and has-let-7b-5p (B) and has-Mir-125a-5p in TCGA database (C). D Correlation between CCL19 and has-Mir-671-5p in TCGA database. E-G Differentially expressed has-let-7b-5p (E), has-Mir-125 A-5p (F) or has-Mir-671-5p (G) in TCGA database. H-J Correlation between OS and HAS-let-7b-5p (H), has-Mir-125 A-5p (I) or has-Mir-671-5p (J) in TCGA database. K-M Correlation between OS and Has-let-7b-5p (K), has-Mir-125 A-5p (L) or has-Mir-671-5p (M) in Kaplan-Meier Plotter online tool (COR< 0.15). “#” represents the miRNAs whose correlation coefficient was less than − 0.15 in the mRNA-miRNA Spearman test and was included in subsequent analysis
