Figure 5. Fecal microbiota in PD patients and in individuals with CI. (A) Shannon and Simpson diversity indexes and (B) score plot of PCoA of PD-CI and CI groups; (C) Significant differentially abundant predicted KEGG metabolic pathways encoded in the fecal microbiota between groups; (D) Number of differentially abundant microbial marker taxa and predicted metabolites between groups. PD: PD patients with normal cognition; PD-CI: PD patients with CI; CI: individuals with CI but not diagnosed with PD; PCoA: principal coordinate analysis; KEGG: Kyoto Encyclopedia of Genes and Genomes.
