Figure 1 (Top panels) Histograms of neointima hyperplasia (NIH) volume in the sirolimus-eluting stent (SES) group (left) and the bare-metal stent (BMS) group (right). A non-Gaussian distribution is demonstrated in both groups (Kolmogorov-Smirnov test: p < 0.0001 for SES group; p = 0.02 for BMS group). The median test evidenced significant differences between groups. (Bottom panels) Histograms of percent volume obstruction in the SES group (left) and the BMS group (right). A non-Gaussian distribution is demonstrated in both groups (Kolmogorov-Smirnov test: p < 0.0001 for SES group; = 0.03 for BMS group). The median test evidenced significant differences between groups.
