Table 2 . Observed agreement between the HECO protocol and the reference protocol for one or more diagnoses.

	HECO/Reference protocola
One or more diagnoses	− / −	+/ −	− /+	+/+	Observed agreement % (95% CI)	κ
Neck/shoulder region	43	5	4	11	86 (77–95)	0.62
Neck	48	5	4	6	86 (77–95)	0.49
Shoulder	48	3	2	10	92 (85–99)	0.75

Elbow/lower arm	58	4	0	1	94 (88–100)	0.32
Wrist/hand	48	4	4	7	89 (81–97)	0.56

Note: Observed agreement in percentage with 95% confidence interval (95% CI) and the kappa coefficients (κ) are given.

^a  − / − , no diagnosis with either protocol;+/ − , positive diagnosis with HECO, no diagnosis with the reference protocol; − /+, no diagnosis with HECO, positive diagnosis with the reference protocol;+/+, positive diagnosis with both protocols.
