Characteristics of peripheral arterial disease patients and control subjects.*

PAD indicates peripheral arterial disease; HDL, high-density lipoprotein cholesterol; LDL, low-density lipoprotein cholesterol; T, telomere repeat copy; S, single-copy gene globin copy.*Data are given as mean ± SD, numbers (percentage) or medians (interquartile range). Telomere length is expressed as a relative telomere/single-copy gene (T/S) ratio.†P value was calculated between PAD patients and control subjects by the two-sample t-test for comparison of continuous variables, the χ2 test for categorical variables, and the Mann-Whitney U test for triglycerides and telomere length.
