2.2. Baseline measures

Data from each participant were collected through study‐specific records and traditional medical forms, consisting of demographic characteristics (age, gender, education level and location), clinical characteristics (BMI, diabetes diagnose date, OADs initiation date, type of OADs used before, diabetes complications, self‐monitoring of blood glucose (SMBG) and hypoglycaemia events) and current treatment regimen (type of OADs and insulin). Baseline fasting plasma glucose (FPG) and HbA1c were tested, and physical examinations (body weight and height) were recorded at each hospital before initiating BI.
