Relative abundance and taxonomic differences of fecal microbiota in the IgAN patients and healthy controls. (a) Microbiome composition in the two groups at the phylum level. (b) Microbiome composition in the two groups at the genus level. The figure shows the top 10 species in each group based on their relative abundances. (c) The predictive model based on the relative abundances at genus level by using a RF model. The importance of each genus in the predictive model was evaluated by the mean decreasing accuracy and the Gini coefficient. (d) ROC curve analysis generated by the RF using 7 genera in the fecal microbiota
