Identification of critical genes associated with LNM. a Kaplan–Meier curve for OS based on lymph node status of patients with CCa in the TCGA cohort. b The volcano plot shows the DEGs between patients with LNM and without LNM. c GO enrichment analysis of the 243 LNM-associated genes. d KEGG pathway enrichment analysis of 243 LNM-associated genes. e Forest plot of LNM-related genes associated with OS. f Pearson correlation analysis was used to determine the correlation among 20 OS-associated genes. The depth of the colour and the size of the circle represent the correlation coefficient between paired genes. Red represents positive correlation and green represents negative correlation
