Correlation between endothelial progenitor cells and pulmonary vascular resistance index (as a reflection of potential vascular disease) in patients with congenital left-to-right shunts. Figure 2A shows the nature of this correlation in the total patient population (n = 74; r = 0.259; p = 0.026); Figure 2B shows the same correlation in patients with Down syndrome (n = 11; r = 0.829; p = 0.002).
