Community structure of the faecal microbiome and metabolome in postgastrectomy and control participants. Principal coordinates analysis (PCoA) with Bray-Curtis distance was performed to assess the community structure of species’ relative abundance obtained by mOTU (A) and MetaPhlAn2 (B) in the gastrectomy group (n=50) (orange) and in the control group (n=56) (blue). The PCoA trend was confirmed by significantly lower microbial structure dissimilarity (Bray-Curtis) within groups (p=5.53×10⁻⁷) (C). PCoA was performed also on faecal metabolite concentrations in the gastrectomy group (n=44) (orange) and the control group (n=54) (blue) (D).
