In OCT follow-up ( achieved in 86.3 % of cases : BuMA , n = 33 ; EXCEL , n = 36 ) , the percentage of stent strut coverage was significantly higher in the BuMA vs. the EXCEL group ( strut level : 94.2 % vs. 90.0 % , p < 0.01 ; p ( non-inferiority ) < 0.0001 ; p ( superiority ) < 0.0001 ) , while the proportion of malapposed struts ( strut level : 1.28 % vs. 1.80 % , p = 0.51 ) and the mean neointimal thickness ( strut level : 0.070.03 mm vs. 0.060.02 mm , p = 0.31 ) were similar .
