(A) Histopathological (trichrome stained), optical coherence tomography (OCT), and quantitative coronary angiography (QCA) images of vessels treated with positive, negative, DEB, and LMDEB. The samples were stained with trichrome. All scale bars indicate 500 µm. (B) Intima to plaque ratios of positive group: 63.04 ± 3.39%, negative group: 1.31 ± 0.57%, DEB group: 50.4 ± 2.86% and LMDEB group: 45.58 ± 4.19%.(p = 0.001 by ANOVA), (C) Percentage of diameter stenosis (DS) of positive group (n = 4): 35.7 ± 2.81%, negative group (n = 8): 6.10 ± 1.37%, DEB group (n = 6): 30.47 ± 6.16%, and LMDEB group (n = 6): 22.65 ± 6.77% (p = 0.002 by ANOVA), (D) Percentage of area stenosis (AS) of positive group: 51.78 ± 5.27%, negative group: 10.08 ± 0.91%, DEB group: 43.95 ± 6.60% and LMDEB group: 38.33 ± 5.32% (p = 0.007 by ANOVA). All data were presented as the mean ± SEM. *p < 0.05, compared with positive group. ^†p < 0.05, compared with negative group.
