Note: *Metabolites were verified by reference standards; avariable importance in the projection (VIP) was obtained from PLS-DA model with a threshold of 1.0; bfold change (FC) was obtained by comparing those metabolites in liver cirrhosis patients to controls; cP values were calculated from Wilcoxon-Mann-Whitney test; dFC was obtained by comparing those metabolites in liver cirrhosis patients with TCM YX Zheng to controls; eFC was obtained by comparing those metabolites in liver cirrhosis patients with TCM SR Zheng to controls; fFC was obtained by comparing those metabolites in liver cirrhosis patients with TCM SR Zheng to TCM YX Zheng. FC with a value >1 indicates a relatively higher concentration present in liver cirrhosis patients or liver cirrhosis patients with TCM YX, SR Zheng while a value <1 means a relatively lower concentration as compared to the controls or TCM YX Zheng subgroup.
