Data are expressed as median (quartile 25–quartile 75). P value results from a Friedman's two-way analysis of variance by rank. ∗ indicates a significantly different value compared to baseline with the Wilcoxon signed-rank test. ICU: Intensive Care Unit; ASAT: aspartate aminotransferase; ALAT: alanine aminotransferase.
