Figure 4 Induction of cytochemokines by coronary artery bypass graft surgery. Reported significances (*p < 0.05, **p < 0.01, ***p < 0.001) were calculated by Bonferroni-adjusted pairwise comparisons with the preoperative level within a repeated measurement analysis of variance model for the respective parameter at three different time points. IL = interleukin; PlGF = placental growth factor; VEGF = vascular endothelial growth factor.
