Association between gut microbial and stool metabolomics. (A) Significant correlations between taxa hits identified by MaAsLin2 for disease status outcome and indoles. (B) Significant correlations between taxa hits identified by MaAsLin2 for disease status outcome and SCFAs. (C) Representative significant associations between metagenomic (DNA) pathways and taxa hits identified for disease status outcome. PD, partial disease.
