	Before	After	Δ (95% CI)	ES	1-β	p
MMSE	28.66 ± 1.23	29.16 ± 1.11	0.50 (0.16; 0.84)	0.53	0.82	0.01
MMSE (results of short memory)	2.38 ± 0.75	2.66 ± 0.55	0.28 (0.02; 0.54)	0.38	0.56	0.04
TFS	14.88 ± 5.63	15.25 ± 4.72	0.38 (-1.29; 2.04)	0.08	0.07	0.65
CTT-I	57.44 ± 25.12	46.09 ± 17.66	-11.34 (-18.38; -4.31)	0.58	0.89	<0.01
CTT-II	113.00 ± 38.69	104.72 ± 31.70	-8.28 (-18.72; 2.16)	0.29	0.35	0.12

Values are means ± SD. Δ, mean difference between measurement after and before the intervention; 95% CI, 95% confidence interval of differences between two measurements; ES, effect size; 1-β, power of the statistical test; MMSE, Mini Mental State Examination—results described in part I mean working memory, and results described in part II mean short memory; TFS, letter verbal fluency (TFS—abbreviation in polish language); CTTI, Color Trails Test—presented data in two parts described in section “Methods”.

Bold values indicated statistical significance (p<0.05).
