Changes of IL-22 in the course of liver disease. Dots indicate serum IL-22 levels in individual patients at baseline (BL) and follow-up (FU), respectively. Corresponding IL-22 serum levels in individual patients at BL and FU are connected. IL-22 serum levels were analyzed in follow-up (FU) sera that were a minimum of 30 days apart from baseline (BL). The dotted horizontal line indicates the upper limit of normal for IL-22 of 18 pg/ml. Comparison between BL and FU was performed with the Wilcoxon matched pairs test.
