(A) Principal component analysis (PCA) plot of feces collected from young control (YC, violet color) and young treatment groups (YP, blue color) showing divergence. (B) Bi-plot showing compounds responsible for divergence. (C) 2D-PLS-DA plot showing spatial division among groups. (D) Key compounds separating YC and YP based on variable importance in projection (VIP) score plot in PLS-DA analysis.
