The expression level of selected transcriptomic signatures and pathways enriched in two subtypes. A Expression level (normalized count) of transcriptomic signatures among two subtypes in SCCH, TCGA and GEO cohorts (Wilcoxon rank-sum test, *p-value < 0.05, **p ≤ 0.01, ***p-value ≤ 0.001, ****p ≤ 0.0001). B The KEGG enrichment pathways ranked by false discovery rate (FDR). Orange represented immune response-associated pathways, green represented immune cell-associated pathways, and red represented tumor suppressor pathways. The top 10 enrichment pathways ranked by normalized enrichment score (NES) in C subtype 1 and D subtype 2
