Table 3

10-fold Cross-Validation results of classification for 212 cases.

CHAID	TN	FP	Sensitivity (%)	Specificity (%)	Accuracy (%)
	FN	TP
Qi deficiency	85	31	69.8%	73.3%	71.7%
	29	67
Phlegm-blood stasis	132	42	86.8%	75.9%	77.8%
	5	33

Note: sensitivity = TP/(TP + FN); specificity = TN/(TN + FP); accuracy = (TP + TN)/(TP + FP + TN + FN).
