HbA1c and FPG were analyzed with categorical variable for the highest tertile.
BMI and VFA were analyzed with categorical variable for criteria of BMI=25, VFA=100, respectively.
*Means adjusted for age, sex, smoking status, BMI, and plaque control record.
†Means adjusted for age, sex, smoking status, and plaque control record.
BMI, body mass index; Coef, coefficient; FPG, fasting plasma glucose; HbA1c, hemoglobin A1c; PESA, periodontal epithelial surface area; VFA, visceral fat area.
