Alpha diversity, Venn diagram and Principle Coordinate Analysis (PCoA) of gut microbiota from HSPN patients and healthy controls at the genus level. (a) Alpha diversity between HSPN patients and healthy volunteers. (b) Veen diagram. There were 293 genera shared between the two groups, while 66 and 56 genera were respectively specific to the HSPN patients and healthy volunteers. (c) The circles and triangles in the PCoA analysis represent the individual samples. The distance between the samples in the figure indicates the degree of difference in the community, showing that the composition of the intestinal bacteria in HSPN patients was substantially different from that of healthy controls
