Relative abundances and comparative analysis of the annotated KEGG functions of gut microbiota in the study subjects. Relative abundances and comparative analysis of the annotated KEGG functions of GM at three levels in HTN and control groups in females (A–C) and males (D–F), respectively. The KEGG functions with significant differences between groups are presented with Wilcoxon rank-sum test. ^#P < 0.1, ^*P < 0.05, ^**P < 0.01
