Additional file 1: Figure S1. Comparative gut microbiome diversity and structure analysis between OA and KBD. (a) Venn diagram of the observed features in OA and KBD. (b) Wilcox-test results for evaluating the relative abundance of significantly different microbiota at the phylum level. (c) Wilcox-test results for evaluating the relative abundance of significantly different microbiota at the genus level. (d) Cladogram indicating the phylogenetic distribution of microbiota correlated with the OA and KBD group. (e) Classification performance of a random forest model using 16s rRNA genus abundance assessed by R random Forest package. (f) ROC curve displaying the top 3 biomarkers for classification between OA and KBD. AUC, area under curve.
