In Table 4, 8 variables including age, alcohol consumption, cigarette smoking, coronary artery lesions, ALDH2 genotype, and clopidogrel, statin and ACEI/ARB use are shown with their p values from univariate regression; among these, only ALDH2*2 (OR = 3.667, 95% CI: 1.606–8.727, p = 0.002) genotype was associated with a significantly increased risk for IRS among patients with diabetes. This evidence concerns the gene ALDH2 and diabetes mellitus.
