Additional file 2 of Metabolomic signatures for visceral adiposity and dysglycaemia in Asian Chinese and Caucasian European adults: the cross-sectional TOFI_Asia study

Additional file 2. Table S1: Internal standard added to extraction solvent for monitoring signal variation during instrumental analysis. Table S2: Data pre-processing parameters for lipidomic profile (XCMS) and HILIC profile (ADAP). Table S3: Differentially expressed lipid species between Caucasian and Asian Chinese. Table S4: Differentially expressed metabolites between Caucasian and Asian Chinese. Table S5: Metabolites associated with FPG in Caucasian and/or Asian Chinese analysed by multiple linear regression adjusted for gender, age and BMI (BH-corrected p<0.05). Table S6: Metabolites associated with %VATTBF in Caucasian and/or Asian Chinese analysed by multiple linear regression adjusted for gender, age and BMI (BH-corrected p<0.05). Table S7: Metabolites associated with FPG and/or %VATTBF in Caucasian analysed by multiple linear regression adjusted for gender, age and BMI (BH-corrected p<0.05). The list of metabolites is ordered by the variable importance in ramdon forest, and the top 100 variables (from unknown X160_HP_241.0719_12.18 to unknown LP_802.5932_348.16) were selected for sample restratification. Table S8: Metabolites associated with FPG and/or %VATTBF in Asian Chinese analysed by multiple linear regression adjusted for gender, age and BMI (BH-corrected p<0.05). The list of metabolites is ordered by the variable importance in random forest, and the top 100 variables (from unknown X160_HP_241.0719_12.18 to PE(P-36:1)) were selected for sample restratification.
