Subjects	Age, gender-adjusted in Model 1		Multivariate-adjusted in Model 2		Multivariate-adjusted in Model 3
	Hazard ratio (95% CI)	P	Hazard ratio (95% CI)	P	Hazard ratio (95% CI)	P
UA (per 1 mg/dL increase)	1.05(1.00∼1.10)	0.05	1.05(0.98∼1.12)	0.15	1.05(0.96∼1.14)	0.34
Gender-specific tertiles of UA
Tertile 1	Reference		Reference		Reference
Tertile 2	1.09(0.89∼1.33)	0.41	1.26 (0.97∼1.65)	0.09	1.23 (0.90∼1.70)	0.19

Abbreviation: UA, uric acid; CI, confidence interval.

Model 1: age,center size-adjusted, gender-adjusted only UA as continuous variable.

Model 2: age,residual renal function, serum albumin, hemoglobin,phosphate, C-reactive protein and center size-adjusted, gender-adjusted only UA as continuous variable.

Model 3: age, residual renal function, serum albumin, hemoglobin,phosphate, C-reactive protein, the histroy of cardiovascular disease,diabetes, body mass index, mean arterial pressure, LDL cholestrol and center size-adjusted, gender-adjusted only UA as continuous variable.
