  1. BMI body mass index, HbA1c hemoglobin Alc, HDL-C high-density lipoprotein cholesterol, LDL-C low-density lipoprotein-cholesterol, SBP systolic blood pressure, SE standard error, TC total cholesterol
  2. † As only BMI and body weight of the patients were reported, height was calculated by: sqrt (weight/BMI).
  3. ‡ The unit of cholesterol was converted by: 1 mg/dl = 0.0259 mmol/l [47]
  4. § For the costs, data are 2022 Chinese yuan, ¥ (2022 US dollar, $), and are presented in the form of rounding to nearest whole number. One US dollar was equal to ¥6.737 in 2022 [19]
