Figure 2. Decreased operational taxonomic units (OTUs) in PsA and Ps gut microbiota.

Figure 2

Several members of the gut microbial communities are underrepresented in PsA and Ps patients at the OTU level. (A) Bacterial OTUs significantly enriched in healthy controls (blue bars) as compared to PsA (red bars) and (B) Ps patients (green bars) were detected by LefSe. Those significant OTUs with q<0.2 after false-discovery rate (FDR) analysis are indicated by asterisks (*). (C) OTUs with distinct abundance in PsA and Ps. (D) Box-plots with relative abundance (parts per unit) of those OTUs marked with * in A–C.
