  1. Data are shown as mean ± SD or number (percentage). Obesity (positive) a body mass index of 30 kilograms divided by height in meters squared (kg/m2) or above, Hypertension (positive) history of treated hypertension or blood pressure ≥ 140/90 mmHg, FBG fasting blood glucose, HbA1c Glycated hemoglobin, OR 95% CI Odds ratio 95% confidence interval. aP value was calculated using total T2DM with and without DF. Student’s t and Chi square/Fisher’s exact tests were used for comparison. Italic values indicate significance at P < 0.05
