Differences between the second (T3) and the first (T1) in vivo test in the experimental and control group, and results of the comparisons between the two groups.

All values are shown as median (25th–75th centile). * r = z/√N; the r value of 0.1, 0.3 and 0.5 indicated a small, medium, and large effect size, respectively; ** within-group statistically significant difference at p ≤ 0.003 (Wilcoxon and Bonferroni correction).
