Table 4.

MID Calculations – analysis derived from baseline and 3-month assessment.

Instrument	MID (SD)^*	MID (ES)^*	AUC (SD)^**	AUC (ES)^**
DASH	18.8 (s: 0.86; e: 0.67)	15.4 (s: 0.43; e: 0.67)	0.832 (p = 0.005)	0.563 (p = 0.48)
MHQ	14.7 (s: 0.81; e: 1.0)	14.7 (s: 0.81; e: 0.57)	0.900 (p = 0.001)	0.748 (p = 0.007)
SF-12	2.5 (s: 0.33; e: 0.86)	2.5 (s: 0.36; e: 0.86)	0.543 (p = 0.71)	0.593 (p = 0.31)

SD = statistical dispersion approach; ES = effect size approach; s = sensitivity; e = specificity; AUC = area under curve.

Sensitivity and Specificity, derived from Receiver Operating Characteristic curve.
