Results of anodal tDCS versus sham stimulation in multivariate analysis.

	Anodal tDCS	Sham	P Value
Change in DOSS scores	2.6‡ (1.91–3.29)	1.26‡ (0.57, 1.95)	0.019†
≥ 2 point improvement in DOSS score	6/7 (86%)	3/7 (43%)	0.107*

^†P value based on a general linear regression model with baseline DOSS, NIHSS, age, time-to-treatment, and stimulation group as covariates.

^‡Least square mean and 95% confidence interval estimated from the general linear model above.

^*P value is based on a logistic regression model with baseline DOSS, NIHSS, age, time-to-treatment and stimulation group as covariates.
