Fig. 2.

Neuropsychological test scores at baseline and 24 weeks in all patients completing the program activity.

Box-plots show median (horizontal line in the box), 25th and 75th percentiles (edges of box), maximum and minimum values (whiskers) and outliers (°). Mini Mental State examination scores appeared substantially unchanged in the experimental group (EG), while tended to decrease in the control group (CG), but the 24-week changes did not show significant differences (A). The EG showed an improvement in Frontal Assessment Battery (FAB) (B), Rey's auditory Verbal Learning Test Delayed Recall (RVTL-D) (C), Raven's Colored Progressive Matrices (CPM) (D) and in completion time for Stroop Word-Color Interference test (SWCT) (E), compared to the CG.
