An Objective Diagnosis Model with Integrated Metabolic and Immunity Parameters for Phlegm-Dampness Constitution

Table 4

Performance of the models distinguishing subjects with PDC from subjects with GC.

Models^1	AUC (95% CI)		Sensitivity	Specificity	Cutoff^3
The metabolic model	0.868 (0.806, 0.929)	<0.001	0.851	0.788	0.433
The immunity model	0.825 (0.727, 0.924)	<0.001	0.786	0.905	0.563
The combined model	0.878 (0.801, 0.954)	<0.001	0.727	0.977	0.610

¹The models were constructed by logistic regression analyses (stepwise, forward). values for the significance of differences between AUCs and 0.5 by the Wilcoxon rank-sum test. ³The optimal cut-point values in ROC (the receiver operating characteristic curve) analyses were defined by the Youden index. PDC: phlegm-damp constitution, GC: gentle constitution, CI: confidence interval, AUC: the area under the curve.
