*The p-values refer to differences between the MD and CD groups concerning the change from baseline to week 12. Differences between the groups were analysed by Mann-Whitney U test. Statistically significant change from baseline to week 12: † p < 0.05, ‡ p < 0.01, § p < 0.001. Within- group differences at week 12 compared to baseline were evaluated by Wilcoxon signed ranks test.
