TCF21 and coronary artery disorder: Spearman's rank correlation results uncovered that CCHE1 level was positively correlated to CAD severity and numbers of vessel lesions (r = 0.388 and 0.671, respectively, p < 0.05), whereas TCF21 displayed a negative correlation to them (r = −0.523 and -0.397, respectively, p < 0.05) (Table 3).
