Linear regression modeling of hand motor outcome and supplementary motor area (SMA) power and CST integrity

Outcome	Predictor	Estimate	95% CI		p‐value
			Lower	Upper
Motor score	Intercept	15.11	−2.72	32.95	.088
	AGE	0.07	0.007	0.14	.034*
	DOM	0.30	−0.54	1.15	.443
	EEG	57.00	24.04	89.97	.003**
	CST‐R	−19.61	−39.15	−0.07	.049*
	EEG × CST‐R	−56.58	−93.53	−19.63	.006**

Note. Linear regression results on composite motor score, with age (AGE), lesion side in relationship to the dominant hemisphere (DOM), relative beta power desynchronization during movement in the ipsilesional SMA (EEG), the FA values of the CST _affected/CST _unaffected ratio (CST‐R), as well as the interaction of EEG and CST‐R. Model results are reported after exclusion of the influential point. Asterisks mark significance level with *p < .05, **p < .01.
