GCG and coronary artery disorder: When glucagon was included as a per standard deviation (SD) increase in Models 1, 2, and 3, each 1-SD increase in fasting glucagon was significantly associated with a 37.1%, 46.2%, and 49.2% higher risk of CAD, respectively (Model 1: OR, 1.371; 95% CI, 1.074-1.750; P < 0.05; Model 2: OR, 1.462; 95% CI, 1.118-1.912; P < 0.01; Model 3: OR, 1.492; 95% CI, 1.099-2.026; P < 0.05).
