Note1. Analyzed by stepwise regression analysis. Considered variables include age, gender, and SUA.

Note2. Dependent variable: MetS, 1, with MetS; 0, without MetS.

^aGender: female = 0, ^bage: 21–30 = 0.

^cAbnormal (male > 7; female > 6 mg/dL) = 1; normal = 0.

^dSubgroups of SUA Tertile 1: SUA < 7 mg/dL, Tertile 2: 7 mg/dL ≦ SUA < 9 mg/dL and Tertile 3: SUA ≧ 9 mg/dL.

^esubgroups of SUA Quartile 1: male SUA < 5 mg/dL and female SUA < 4 mg/dL.

Quartile 2: male 5 mg/dL ≦ SUA < 6 mg/dL and female 4 mg/dL ≦ SUA < 5 mg/dL.

Quartile 3: male 6 mg/dL ≦ SUA < 7 mg/dL and female 5 mg/dL ≦ SUA < 6 mg/dL.

Quartile 4: male SUA ≧ 7 mg/dL and female SUA ≧ 6 mg/dL.
