Gut microbiota analysis of patients with central and lateral cervical lymph node metastasis. The number of common and unique OTUs in N, A1, and B1 (A). The relative ratio of top abundant taxa in N, A1, and B1 at the phylum level (B). The relative ratio of top abundant taxa in N, A1, and B1 at the genus level (C). Significantly differential taxa in N, A1, and B1 at the phylum level (D). Significantly differential taxa in N, A1, and B1 at the genus level (E). Linear discriminant analysis (LDA) effect size (LEfSe) analysis of fecal microbial genus in N, A1, and B1 (F). N: Location without lymph node metastasis, A1: Central lymph node metastasis, B1: Lateral lymph node metastasis.
