^a Data are presented as Mean ± SD, Change values (CV), Measured values (MV)—Baseline values at different follow-up times.

Statistics: p-values were calculated with Wilcoxon–Mann–Whitney test. Differences at baseline were compared based on measured values (MV) in both groups, while differences between both groups at different follow-up time points were compared based on change values (CV).
