Inverse Relationship between Serum VEGF Levels and Late In-Stent Restenosis of Drug-Eluting Stents

Figure 1

Comparison of serum VEGF levels between patients with ISR and without ISR in the late and very late phases. Data are presented as box plots with medians and interquartile ranges. values were calculated using the Mann–Whitney test. No significant difference was found between the L-non-ISR and VL-non-ISR groups. VEGF = vascular endothelial growth factor; ISR = in-stent restenosis; L-ISR = late in-stent restenosis; VL-ISR = very late in-stent restenosis.
