Construction of LMRGs prognostic model and survival analysis. (A) The Venn diagram shows the intersection between LMRGs and DEGs. (B) The heatmap depicts the relative expression of 23 genes involved in lactate metabolic activities that were shown to vary between tumor and normal specimens. (C-E) In the TCGA, GEO, and FJZL cohorts, low-risk group patients had a favorable OS rate as opposed to those in the high-risk group. (F) The ROC curve for HNSCC patients’ OS over 1, 3, and 5 years in the TCGA, GEO, and FJZL cohorts. (G) Construction of a nomogram based on riskscore and clinical characteristics. (H) Calibration curves of the nomogram for predicting OS in TCGA-HNSCC patients. (I) Correlation analysis of clinical features and risk score
