Box plots of plasma level of miR-126 in patients with angiographically significant CAD (n = 31) and patients without CAD (n = 36). TaqMan miRNA assays were performed on RNA isolated from plasma obtained from the 2 different groups. No significant difference was observed about the plasma miR-126 levels (p = 0 .675). The level of plasma miR-126 is normalized to miR-16. The lines inside the boxes denote the medians. Mann-Whitey U test or Kuskall-Wallis test was used to determine statistical significance.
