tHcy – total homocysteine; MS – metabolic syndrome; Ref – reference; OR – odds ratio; CI – confidence interval; SD – standard deviation. Model I adjusted for age and sex. Model II:
a
adjusted for sex, smoking and drinking status, eGFR, reduced HDL-C and abdominal obesity.
b
adjusted for a + serum uric acid.
c
adjusted for b + age and elevated TG.
d
adjusted for age, sex, BMI, smoking and drinking status, eGFR and tHcy.
e
adjusted for d + heart rate and serum uric acid.
