Glucose concentrations during the oral glucose tolerance test according to the combined model of genetic variants (GCK and INSR) and chronic heavy alcohol consumption. P values for glucose levels at 0 min, 1 h, and 2 h post-OGTT were calculated by general linear models with adjustment for age, physical activity, smoking status, BMI, and follow-up period. Significant differences of means among genotype-alcohol consumption groups by Duncan test (a: highest mean; c: lowest mean; a > b > c).
