Spearman′s correlation coefficients (R) computed between scores of the NCS-R-PS and NCS-R-SS and mean differences (MD) for the two experimenters. * p < 0.05.

Assessment Timing	NCS-R score	Spearman Correlation Coefficient		Mean Difference PS—SS
		Experimenter 1	Experimenter 2	Experimenter 1	Experimenter 2
Baseline	Motor	R = 0.520 *	R = 0.428 *	MD = 1 *	MD = 1
	Verbal	R = 0.814 *	R = 0.845 *	MD = 1 *	MD = 1 *
	Facial	R = 0.590 *	R = 0.556 *	MD = 1.5 *	MD = 1 *
After 1 month	Motor	R = 0.571 *	R = 0.654 *	MD = 1 *	MD = 1 *
	Verbal	R = 0.776 *	R = 0.779 *	MD = 1	MD = 1
	Facial	R = 0.618 *	R = 0.622 *	MD = 1*	MD = 1.5 *
After 3 months	Motor	R = 0.417 *	R = 0.353 *	MD = 1	MD = 0.5
