  1. Data are expressed as relative values (%): mean % of total FA ± SD from two independent experiments conducted in triplicate for each CAD patients and controls
  2. Σ Trans FA sum of trans fatty acids, Σ cis FA sum of cis fatty acids
  3. A significant difference between controls and patients is indicated by *(p < 0.05) and **: p < 0.001. The Mann-Whitney test was used
