Fig. 1From: Reduced fecal short-chain fatty acids levels and the relationship with gut microbiota in IgA nephropathyThe gut microbiota composition of IgAN patients was significantly different from that of the control. The α-diversity of the microbiota presented as Chao1 (P = 0.0945, A), observed species (P = 0.051, B), Simpson (P = 0.067, C) and the Shannon index (P = 0.033, D). The β-diversity in the IgAN and control groups was calculated by NMDS (Stress = 0.132) (Fig. 1E)Back to article page
