Specific alterations in gut microbiota and plasma metabolites among GA, SLE and RA. The differences of α-diversity by Kruskal-Wallis H test for Shannon index in fungi (A) and Chao in bacteria (B) index among control, GA, GA_MD, SLE and SLE_MD groups. (C) The plot depicted the composition of the differential bacterial genera in the three types disease comparison groups. G1, RA_MD vs. RA, G2, GA_MD vs. GA, G3, SLE_MD vs. SLE, (D) The classification of differential metabolites in G1, G2 and G3 groups. (E) Stacked bar charts showed metabolism pathways and classification of differential metabolites enrichment in three groups
