Minimal important change (MIC) and its corresponding sensitivity and specificity for sample I and II

	Sample I			Sample II
	MIC	Sensitivity	Specificity	MIC	Sensitivity	Specificity
ProFitMap-neck
Symptom-intensity index	9.9	0.71	0.78	6.6	0.76	0.87
Symptom-frequency index	13.6	0.64	0.83	11.0	0.72	0.85
Function index	11.2	0.71	0.75	7.3	0.80	0.66
Total score	9.6	0.76	0.75	7.1	0.80	0.79
NDI	6.3	0.62	0.75	5.2	0.82	0.75

Sensitivity was defined as the rate of correctly classifying improved participants, and specificity as the rate of correctly classifying not or little changed participants. Minimal important change was determined as the change score that showed the highest combination of sensitivity and specificity
