	Control		Treatment
	M or count	SD or %	M or count	SD or %	Diff	95% CI
(1) Age	68.11	6.24	67.68	2.77	-0.42	[-2.55, 3.41]
(2) Years of education	17.47	2.38	17.09	2.20	-0.38	[-1.83, 1.07]
(3) MoCA	27.21	2.39	27.77	1.93	0.56	[-0.81, 1.92]
(4) Vocabulary	0.63	0.23	0.68	0.18	0.04	[-0.09, 0.17]

MoCA is Montreal Cognitive Assessment (Maximum = 30, Range = 24–30). Vocabulary is scored as the proportion of accurate items on the ETS Extended Range Vocabulary Test. Diff = mean difference between groups at baseline. There were no significant differences between the treatment and control groups at baseline.
