A–H Consensus matrix plots for k = 2 to 9. I Consensus clustering CDF for k = 2 to 9. J Relative change in area under CDF curve for k = 2 to 9. K = 2 was determined as the optimal clustering number. K Histograms of each sample when k ranges from 2 to 9. L The Kaplan–Meier survival analysis for the two clusters. M The heatmap of DEG expressions of the two clusters and clinicopathological features between the two clusters. N Comparison of the tumor grades between the two clusters. O The bar graph displays the expression differences of MTFR2 and DNM1L between the two clusters. P Barplot graph for GO enrichment and KEGG pathway analysis. CDF cumulative distribution function, DEG differentially expressed gene, GO Gene Ontology, KEGG Kyoto Encyclopaedia of Genes and Genomes, BP biological process, CC cellular component, MF molecular function. ** P < 0.01, *** P < 0.001
