The alteration of gut microbiota was closely associated with the bile acid levels. (A) Pearson’s correlations of retinol and retinene levels with the levels of (a) CA, (b) LCA and TUDCA. Red indicates a positive correlation, and blue indicates a negative correlation. (B) Spearman’s correlation analysis of differential genus microbiota levels with CA, LCA and TUDCA levels. (C) Spearman’s correlation analysis of Ruminococcaceae_NK4A214_group abundance with (a) CA, (b) LCA and (c) TUDCA levels. CA, cholic acid; LCA, lithocholic acid; TUDCA, tauroursodeoxycholic acid.
