(a) and (b) show , , and as well as the proportional contribution of each JPT category. Values are in thousands of dollars and indicate the unnecessary annual economic cost resulting from an incorrect diagnosis.

(a)

Anti-CC test	Actual RA condition
Result	Diseased	Not diseased
Positive	0	−0.55 (−0.56–−0.44)	= −0.55 (−0.56–−0.44)
Negative	−9.6 (−9.7–−9.5)	0	= −9.6 (−9.7–−9.5)
			= −5.1 (−5.1–−5.0)

(b)

RF test	Actual RA condition
Result	Diseased	Not diseased
Positive	0	−1.4 (−1.5–−1.3)	= −1.4 (−1.6–−1.3)
Negative	−9.5 (−9.6–−9.4)	0	= −9.5 (−9.6–−9.4)
			= −5.5 (−5.5–−5.5)
