  1. Abbreviations: BP blood pressure; LDL-C LDL-cholesterol; AOR adjusted odds ratio; CI confidence interval.
  2. Weighted to represent the Korean population with diabetes, aged 20 years or older.
  3. 1 Proportion of subjects who reached HbA1c < 6.5%, BP <130/80 mmHg, LDL-C <100 mg/d.
  4. 2 Proportion of subjects who reached HbA1c < 6.5%, BP <130/80 mmHg, LDL-C <100 mg/d in each category of each variable.
  5. 3 AORs were obtained after adjusting for age, gender, education level, household monthly income, duration of diabetes, self-reported health status, regular exercise, and body mass index.
