CBS affects the gut microbial diversity and composition of obesity-related hypertensive rats. a, b α-Diversity Chao1 index and Shannon index (n = 4–7). c Principal coordinate analysis (PCoA) score plot based on unweighted UniFrac metrics. d Relative abundances of the top 20 dominant phyla. e Relative abundances of the top 20 dominant genera. f Heatmap of the relative abundance of the top 50 dominant genera for each sample. g Cladogram generated from LEfSe analysis. h Bar graph of the linear discriminant analysis (LDA) score distribution showing genera with LDA scores greater than the set value of 3. i Heatmap of Spearman correlation analysis of the 30 microbes associated with obesity-related parameters and blood pressure. The Spearman rank correlation coefficient (r) ranged from − 1 (blue) to 1 (red). *P < 0.05, **P < 0.01, ***P < 0.001 A, B Statistical comparison: Kruskal–Wallis test
