  1. Normally distributed values in the table are given as the mean ± SD, non-normally distributed values are given as the median (25% and 75% interquartiles), and categorical variables are given as frequency (percentage).
  2. DM/–DPN group: well-controlled type 2 diabetes without DPN; DM/DPN group: well-controlled type 2 diabetes with DPN.
  3. BMI: body mass index; SBP/DBP: systolic/diastolic blood pressure; TC: total cholesterol; TG: triglyceride; HDLC: high density lipoprotein cholesterol; LDLC: low density lipoprotein cholesterol; HbA1c: glycosylated hemoglobin A1c; ISI: insulin sensitivity index; eGFR: estimated glomerular filtration rate; SDBG: standard deviation of blood glucose; MODD: mean of daily differences; MAGE: mean amplitude of glycemic excursions.
