(A) CD34⁺/CD133^–/KDR⁺/OCN⁺ cells, expressed as absolute counts per 100,000 counts, and (B) percentage of OCN⁺ of CD34⁺/CD133^–/KDR⁺ cells in control subjects (circles), patients with ECA (triangles), and in patients with LCA (squares). *p < 0.05, **p < 0.01, and ***p < 0.001 compared with control subjects. Shown are the median values and interquartile ranges. Abbreviations as in Figures 1 and 2.
