Notes: Values expressed as the mean (standard deviation); Δ, variation after 90 days of intervention; there was no statistical difference between groups during pre-intervention (P>0.05); comparison before and after intervention (Wilcoxon’s test); variable comparison between groups (Mann–Whitney U-test). Values are in bold are statistically significant.
