(Table 2 summarises and compares (GS versus C) biomarkers of energy-, carbohydrate and lipid metabolism of all subjects of the BiliHealth study.
Values are specified as applies according to distribution of data. For parametric variables, means° ± sd are shown, for non-parametric data, medians^ (50th percentiles) and inter-quartile range (IQR) are displayed. Comparison of means for parametric data or of ranks (for non-parametric data) was completed using independent samples t-test or Mann-Whitney-U-test. P-value*: significant on a 5% level of significance; p-valueT: trend on a 10% level of trend
