| fasting blood glucose | Fasting plasma glucose (FPG) were measured using the enzymatic colorimetric method. | 12 Weeks |
| HbA1c | Glycated hamoglobin (HbA1c) was measured by a colorimetric method after an initial separation by ion exchange chromatography (Biosystem, Barcelona, Spain). | 12 Weeks |
| HOMA-IR | Insulin resistance was evaluated by homeostasis model assessment of insulin resistance (HOMA-IR), which was calculated by using the following formula HOMA-IR = [fasting insulin (mU/l) × FPG (mmol/l)]/22.5 | 12 Weeks |
