Data are presented as mean ± SD if normally distributed and as median with first and third quartile if not normally distributed.
An intention-to treat analysis was performed. P-overall corresponds to the p-value of paired one-way ANOVA.
By p-overall<0.05, post-hoc Tukey’s test between groups were performed. Superscript letters (a,b,c,d) indicate p<0.05 in post-hoc t-test between the subject group of the column in which the letters are written vs. the group indicated by the letter (a, b, c or d)
