Post hoc tests comparing different timepoints within group (intervention or control) and comparisons between group for each timepoint (intervention vs. control). All results were controlled for age and sex. CG, control group (n = 10); IG, intervention group [(n = 18) n = 16 at T6]; t, t-statistic; T0, T2, T4, and T6, examination timepoint after 0, 2, 4, and 6 months.
