We performed logistic regression analyses of alcohol intake with respect to the risk of an HbA1c level of ≥5.7%, ≥6.1%, and ≥6.5% using age, sex, FPG concentration, college graduation, smoking history, presence of hypertension, waist circumference, serum total cholesterol concentration, serum HDL cholesterol concentration, serum TG concentration, presence of anemia, serum WBC count, and serum ALT concentration as covariates. Here, GPT is linked to anemia (phenotype).
