MeasureTime frame
1. Systolic and diastolic blood pressure are measured using a digital sphygmomanometer (A&D Medical, Tokyo, Japan) after at least 5 minutes of seated rest at baseline and 12 weeks. 2. Fasting plasma glucose is measured using an automated chemistry analyser (BK-200, Biobase, China) from venous blood samples collected after an overnight fast of at least 8 hours at baseline and 12 weeks. 3. HbA1c is measured using a fully automated glycated haemoglobin analyser (BK-HbA1c, Biobase, China) at baseline and 12 weeks. 4. Lipid profile parameters (triglycerides, TC, LDL, and HDL) are measured using an automated chemistry analyser (BK-200, Biobase, China) at baseline and 12 weeks. 5.
