Table 1. The phenotypic characteristics of the study population.
| CAD-positive | CAD-negative | P | |
| N | 425 | 258 | |
| Gender (M, %) | 62.1 | 44.2 | <0.001 |
| Age (y) | 63.2±9.1 | 62.0±10.0 | 0.06 |
| BMI (kg/m2) | 26.1±3.5 | 25.8±3.7 | 0.39 |
| T2DM duration (y) | 8.44±7.1 | 8.51±7.0 | 0.76 |
| FPG (mmol/L) | 7.2±2.6 | 6.9±2.1 | 0.35 |
| Dislipidemia History (positive, %) | 78.7 | 74.0 | 0.24 |
| Hypertension history (positive, %) | 78.3 | 73.1 | 0.18 |
| Smoking history (positive, %) | 50.2 | 29.3 | <0.001 |
Data are presented in mean ±s.d. BMI: body mass index; FPG: fasting plasma glucose; CAD: coronary artery disease; T2DM: type 2 diabetes. The fasting plasma glucose values were after intervention. Independent t test was used to evaluate age and BMI; Mann-Whitney U test was used to compare the difference of T2DM duration and FBG between the two groups.
