Changes in plasma metabolites. Biplot of redundancy analysis (RDA axis 1 vs axis 2) of the plasma metabolite data constrained by butyrate and allogenic FMT treatment variables (before, baseline, and 4 weeks after treatment). Baseline plasma metabolites in the post-RYBG feces donors is also shown. The brackets on the axis labels refer to the proportion of the constrained variance explained by the respective axis/RDAs. In this case, the constrained variance was 7.8% of the total variance.
