Contribution of dietary intake to the levels of HFS-related amines in CRT. (A) Heatmap showing the correlations between HFS-related amine metabolites and dietary intake. Statistical significance was set as: *p <  0.05, **p < −0.01 (Spearman correlation). Red boxes represent positive correlations, and blue boxes represent negative correlations. (B) Boxplots show the relative levels of amine-related dietary intake. The Student’s t-test was used to examine the relationship between dietary intake for groups HFS0, HFS1, and HFS2/3, and significance was set as: *p <  0.05, **p < −0.01.
