Gut microbiome dysbiosis in tinnitus group. (A) A Venn diagram demonstrating the existence of ASVs in the tinnitus and healthy groups. The area where two circles intersect indicates the number of ASVs shared between the two groups. (B) Significant differences existed in alpha-diversity between the two groups, including Chao1, observed_otus, and goods_coverage. Wilcoxon rank-sum test was used. (C) The PCoA was performed using an unweighted UniFrac matrix. (D) UPGMA cluster diagram. The UPGMA is based on unweighted UniFrac metrics.
