  • 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.
