  1. Data are mean ± standard deviation or absolute number with percentages. P-values for overall one-way ANOVA are shown
  2. aHypertension was defined as a systolic blood pressure of 140 mmHg or above, a diastolic blood pressure of 90 mmHg or above or use of anti-hypertensive medication
  3. bCurrent blood glucose level was measured using a finger prick
  4. cAlbumin-to-creatinine ratio was determined in 24-h urine sampling
  5. dNeuropathy was self-reported or obtained from medical records
  6. eNephropathy was based on a 24-h urine sample and defined as an ACR of 2.5 or above for men and 3.5 for women
