Interrater and test-retest reliability, SEM, and MDC of NCWT results.

	Inter-rater ICC3,2 (95% CI)	value	Test-retest ICC2,1 (95% CI)	value	SEM	MDC
NCWT completion time	1.000 (1.000-1.000)	<0.001	0.938 (0.879-0.970)	<0.001	2.48	6.87
NCWT steps	0.987 (0.972-0.994)	<0.001	0.864 (0.734-0.933)	<0.001	1.98	5.50

. CI: confidence interval; ICC: intraclass correlation coefficient; MDC: minimal detectable change; SEM: standard error of measurement.
