Table 6.

Results by diagnosis in Tests 1 and 2. Percent exactly correct and correct or acceptable replies with relative sensitivity or specificity (with 95% CI). The results for cancer are sensitivities and relative sensitivity. The results for benign are specificities and relative specificity between Test 1 and Test 2. The results for cancer for “Correct or acceptable” are as for the results for “Correct”

	Correct			Correct or acceptable
	Test 1	Test 2	Relative sensitivity/specificity	Test 1	Test 2	Relative sensitivity/specificity
Cancer	30.6 (28.0–33.4)	49.5 (46.6–52.5)	1.62 (1.44–1.81)
Benign	32.4 (30.6–34.3)	47.4 (45.4–49.4)	1.46 (1.36–1.58)	74.3 (72.6–76.1)	82.5 (81.0–84.0)	1.11 (1.07–1.15)
