Table 2. The AUC-ROC for the logistic regression models.

	AUC-ROC	(95% CI)	P-value
Basic model
Adjusted for age, gender, and five components of metabolic syndrome (waist circumference, systolic blood pressure, fasting plasma glucose, triglycerides, and high-density lipoprotein cholesterol)	0.833	(0.738, 0.928)	Reference
Fully adjusted model
Adjusted for basic model plus retinal vessel calibers	0.863	(0.779, 0.947)	0.142
Noninvasive examination model
Adjusted for noninvasive examination of derived parameters of age, gender, waist circumference, and systolic blood pressure plus retinal vessel calibers	0.813	(0.719, 0.906)	0.581

Abbreviations: AUC-ROC, area under the receiver operating curve; CI, confidence interval.
