Geometric Means, Variances and Intraclass-Correlation Coefficients (ICCs) of Serum Concentrations of Acylcarnitines Measured 4 Months Apart Among 100 Healthy Subjects from the EPIC-Potsdam Cohort.

aAbbreviations are as follows: Cx:y (x = number of carbons in the fatty acid side chain, y = number of double bonds in the fatty acid side chain), decarboxyl (DC), hydroxyl (OH). For detailed nomenclature see Table S1.bn = 100.cA paired t-test based on log-transformed values was calculated to compare geometric means of metabolite concentrations over-time.dBased on log transformed values.eICC calculated as the ratio of between-person variance and total variance.fFor negative values ICC was calculated based on positive variance estimators [33].gMetabolite concentration was below the assay's limit of detection.
