Friedman analysis of variance with repeated measures on condition (ie, baseline vs non-noxious vs noxious)

NCS	Baseline	Non-noxious	Noxious	χ²	p Value
Total	0.92±1.19	1.48±1.37	4.77±1.84	101.46	<0.0001*
Motor	0.14±0.35	0.21±0.45	1.63±0.83	96.35	<0.0001*
Verbal	0.09±0.39	0.06±0.30	0.37±0.70	20.28	<0.0001*
Visual	0.34±0.82	0.98±1.05	1.25±0.97	47.41	<0.0001*
Facial	0.34±0.54	0.25±0.51	1.43±0.82	73.48	<0.0001*

Asterisk marks significant difference (*p<0.01; Bonferroni corrected p value threshold).
