Data are presented as means ± SD for continuous variables and percentages for binary variables. †-value is for testing the trend with adjustment for sex and age. AGEs, advanced glycation end-products; ALT, alanine aminotransferase; AST, aspartate aminotransferase; BP, blood pressure; Est. CCR, estimated creatinine-clearance rate; HDL-C, HDL cholesterol; hs-CRP, high-sensitivity C-reactive protein; LDL-C, LDL cholesterol; sd, small-dense; TC, total cholesterol; UA, uric acid.
