Data represent mean ± SD. p value LMM, Significance between groups in Linear Mixed Model testing assessing treatment × time interaction. ** p < 0.01; *** p < 0.001 within the group from baseline to final examination (Wilcoxon signed-rank test). LMM: linear mixed model. Bold numbers represent statistical significance of primary endpoints
