Comparison of the demographic and biochemical data between the high and normal ABI groups.

Values are expressed as mean ± S.D., median (25%–75% percentiles) or as percentage (%) of patients. P-value based on Pearson chi-square for categorical variables and t-test for normally distributed data is for comparison between the high and normal ABI groups (*P<0.05). Mann–Whitney U test is used to compare nonnormally distributed variables between the high and normal ABI groups (*P<0.01). Abbreviations: ABI, ankle-brachial index; BMI, body mass index; ALP, alkaline phosphatase; Ca, calcium; P, phosphate; Cr, creatinine; UA, uric acid; TC, total cholesterol; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol; TG, triglycerides; apo, apolipoprotein; hsCRP, high-sensitivity C-reactive protein; FPG, fasting plasma glucose; CHE, cholinesterase.
