Variance decompositions of LC-MS/MS serum and NMR urine metabolic profiles. Using a partial R2 approach, regression models were performed on each of the 44 urinary metabolites and on each of the 177 serum metabolites. Variables included in the model: batch (analytical), run order (analytical), time of sampling (urine pre-analytical), postprandial interval (serum pre-analytical), sample processing time (pre-analytical), sex (demographic), age (demographic), BMI z-score (demographic), ethnicity (demographic), 11 dietary intake frequencies (dietary) and cohort
