Cost-Saving Early Diagnosis of Functional Pain in Nonmalignant Pain: A Noninferiority Study of Diagnostic Accuracy

Table 2

Noninferiority comparison of peg and electronic algometry in discerning functional from nociceptive pain: areas under the receiver operating characteristic curves (AUC).

	AUC in % of a perfectly discerning test (95% CI)		Difference (95% CI) value
	Peg algometry	Electronic algometry	Crude	AUC of peg minus 95% of the AUC of electronic algometry
Finger measures	79 (71 to 86)	72 (64 to 80)	7 (−3 to 16) 0.18	11 (1 to 20) 0.04
Ear measures	81 (74 to 88)	66 (57 to 75)	15 (5 to 24) 0.003	18 (8 to 27) < 0.001
