The overall association scores of CHI3L1 in coronary artery disease, peripheral arterial disease, carotid atherosclerosis, and atherosclerosis were 0.102, 0.091, 0.064, and 0.062, respectively, which are similar to the overall association scores of VCAM1 and ITGAX (Table 4). This evidence concerns the gene CHI3L1 and peripheral arterial disease.
