Endothelial progenitor cells and plaque burden in stented coronary artery segments: an optical coherence tomography study six months after elective PCI

Table 5 Multiple linear regression model (R ² 0.235, F 2.675, p = 0.048) for EPC and possible covariates for coronary plaque burden (total plaque volume): similar significant results were found for the other investigated EPC subpopulations and for plaque surface area
