After adjustment for traditional risk factors for CAD [gender, age, BMI, W, systolic blood pressure (SBP), diastolic blood pressure (DBP), TC, TG, HDL-c, LDL-c, eGFR, CRP, HOMA-IR, FPG, 2hPG, smoking status, family history of CAD, hypoglycemic therapy, anti-hypertensive therapy, and lipid-lowering therapy], the results showed that HbA1c [odds ratio (OR) = 1.343, 95% confidence interval (CI): 1.007-1.791, P = 0.044], 1,5-AG (OR = 0.957, 95% CI: 0.927-0.989, P = 0.008), and GA (OR = 1.143, 95% CI: 1.048-1.247, P = 0.002) were all the factors contributing to CAD. Here, CRP is linked to coronary artery disorder.
