  1. Values are regression coefficient (β) ± SE, derived from multiple linear regression analyses of coronary flow index with central aortic systolic, diastolic and mean blood pressure, respectively, after adjustment for gender, age, body mass index, current smoking, history of hypertension and dyslipidemia, prior myocardial infarction, severity of coronary artery disease, GFR, total and HDL cholesterol ratio, log-transferred hsCRP and left ventricular ejection fraction. P values for interaction in group of mild, intermediate and severe stenosis of PCDA are given
  2. GFR glomerular filtration rate, HDL high-density lipoprotein, hsCRP high-sensitivity C reactive protein, PCDA predominant collateral donor artery
  3. * P < 0.001, # P < 0.01 and & P < 0.05 vs. the corresponding β value in non-diabetes
