  1. Average and SD (standard deviations) for NOR patients (normal patients without clinically significant coronary artery disease) and CAD patients (patients with coronary artery disease requiring therapeutic percutaneous intervention) are shown. N = number of samples for which parameters were available. P = statistical P values for individual continuous parameters between the NOR and CAD groups with adjusted false discovery rate (FDR) cut-off for significance ≤ 0.01. P values for categorical values were determined by Pearson's χ2 test. NS indicates that no significant statistical differences were detected. M/F indicates the number of males and females in each group with age expressed in years, WT (weight) in kg and HT (height) in cm.
  2. DIAB (diabetes) and HYPTX (hypertension) reported as the number of positive (Y) or negative (N) patients per group.
  3. BSA = body surface area calculated in m2; BMI = body mass index (weight in kg/height in m2); CREAT = creatinine, mg/dl; CHOL = cholesterol, mg/dl; EF% = ejection fraction, percentage; HDL = high-density lipoprotein, mg/dl; LDL = low-density lipoprotein, mg/dl.
