Data is noted as R-squared and p values for each regression analysis. A p value  ≤ 0.01 is considered significant and marked in bold. Raw: unadjusted analysis. Demographic: adjusted for demographic factors: age and sex. Diabetes: adjusted for diabetes factors: disease duration, haemoglobin A1c and use of insulin. Cardiovascular: adjusted for cardiovascular risk factors: BMI, smoking, hypertension, and use of antihypertensive medications. All: adjusted for both demographic, diabetes and cardiovascular

SDNN standard deviation of all normal inter-beat interval; SDANN standard deviation of the averages of interbeat intervals; SDNNi mean standard deviation of the averages of inter-beat interval for each 5-min interval; VLF very low frequency; IL interleukin; sICAM soluble intercellular adhesion molecule; VEGF vascular endothelial growth factor
