Data are shown as mean and standard deviation adjusted by age and distance
EG, experimental group; CG, control group; SD, standard deviation
Factorial ANOVA analysis (study group, sex and assessment time point). Pair comparisons by Bonferroni test. Statistical differences (p < 0.05). Statistical signals are presented in the higher mean of the pair comparisons: ^aEG vs CG; ^b boys vs girls and ^cbaseline vs follow-up
