Mental Regression (AMR). Without Mental Regression (ANMR). The data are expressed as means ± DS. Mixed-Designs ANOVA with Sidak correction used to compare differences among the groups. P < 0.05 value in bold, was considered for significant results. p^a. p between AMR and ANMR at baseline; p^b: p between AMR and ANMR at 24 months of follow-up;

^*p < 0.05 between baseline and 24 months of follow-up (intragroup).
