Table 3. Area under the curve (AUC) of cmetS-Z and cmetS-PCA as predictors for MetS (defined as the presence of > = 3 risk factors), as compared to that using the individual components as predictors.

AUCs using these predictors to predict an emerging state of MetS (defined as the presence of > = 2 risk factors) are also presented.

	cmetS-Z	cmetS-PCA	Waist circumference (cm)	Systolic blood pressure (mmHg)	Saliva HDLC (mg/DL)	Saliva Glucose (mg/DL)
AUC (Risk factor > = 3)	0.935	0.912	0.892	0.844	0.851	0.593
AUC (Risk factor > = 2)	0.900	0.917	0.894	0.841	0.593	0.513
