* Values presented as: Median (Median absolute deviation); a, b, medians assigned different superscripts indicate significant differences (\(p<0.05\)) between the dietary treatments; KW: Compounds that were found to be significantly different (\(p<0.05\)) due to different dietary treatment, following the Kruskal–Wallis Test; LDA: Compounds that belong to the minimal set of 14 compounds that lead to a complete separation of the three dietary groups in linear discriminant analysis, i.e., to a confusion matrix with kappa = 1; nd: not detected.
