Metabolite composition analysis of patients with central and lateral Cervical lymph node metastasis. Metabolite composition classification in F1 and T2 (A). Volcano map of differentially expressed metabolites in F1 and T2 (B). KEGG enrichment analysis and related DEMs in F1 and T2 (C). Differentially expressed metabolite bar graph in F1 and T2. Horizontal coordinates are log2FC of differential metabolites, and vertical coordinates are differential metabolites (D). ROC curve analysis of the candidate biomarkers shows the abundance of three metabolites and the high AUCs for the three metabolites (E). F1: Number of lymph node metastases is less than 5, T2: Number of lymph node metastases exceeds 10.
