Table 2. Association of biomarkers with prevalent metabolic syndrome.

	Model 1		Model 2
Biomarker	OR (95% CI)	p-value	OR (95% CI)	p-value
ADMA	1.13 (1.04, 1.22)	0.002	1.08 (0.96, 1.22)	0.19
SDMA	0.94 (0.87, 1.02)	0.16	1.15 (1.01, 1.30)	0.032
L-Arginine	0.97 (0.90, 1.05)	0.45	1.05 (0.94, 1.17)	0.39
ARG/ADMA	0.89 (0.82, 0.97)	0.004	0.99 (0.89, 1.11)	0.92

Data are displayed as odds ratios (95% confidence intervals) per 1 standard deviation increase in the respective biomarker.

Model 1 is adjusted for age, sex, smoking, and eGFR.

Model 2 includes the adjustment variables in Model 1 plus waist circumference, SBP, DBP, glucose, HDL cholesterol, and triglycerides.
