Diagnostic accuracy of pattern differentiation algorithm based on Chinese medicine theory: a stochastic simulation study

Table 2 Confusion matrices for comparison of binomial proportions between the two diagnostic tests

	TN (no single pattern simulated)				TP (single pattern simulated)
	Test 1	-	+		Test 1	+	-
Test 2	-	A	B	Test 2	+	a	b
	+	C	D		-	c	d

TN: true negative, TP: true positive
(+) and (-) indicate positive and negative test results respectively.
B is the number of TN cases classified correctly by test 2 and falsely by test 1 and conversely for C cases and analogously for the TP group.
