Additional file 1 of Identification of candidate metabolite biomarkers for metabolic syndrome and its five components in population-based human cohorts

Additional file 1: Table S1. Metabolite quantification and normalization in KORA F4. The table presents metabolite abbreviations, analyte classes, and biochemical names of 163 metabolites in columns first to third. Detecting rate of each metabolite in 3,061 KORA F4 individuals is shown in the fourth column. Column fifth displays the median coefficient of variation of 114 quality control samples. The sixth column displays the percentage of 3061 KORA F4 study individuals with values at or above the limit of detection. The final column displays each metabolite’s used/excluded status. Table S2. Logistic regression results of MetS-associated metabolites with each of the 5 components in the KORA study. Odds ratioswith 95% confidence interval. Significant P-value < 0.05/56 = 8.93E-04 are shown in bold. Table S3. Metabolic network of PCs and LPCs. Table S4. Metabolic network of BCAAs. Table S5. Metabolic network of Ser, Gly, Phe, and Tyr.
