A total of 20 patients were randomly assigned to stenting with BP-SES (n=11) or EES (n=9).
Overall intravascular imaging was available for 15 (75%) patients. The primary endpoint was the difference in
rate of uncovered struts between BP-SES and EES. To account for strut-level clustering, the results in both
treatment groups were compared using a generalized linear mixed model approach.
Results: Regarding the primary endpoint, BP-SES as compared to EES showed similar rates of uncovered struts
(37 [6.8%] versus 167 [17.5%], odds ratio (OR) 0.45 (95% CI 0.09-2.24), p=0.33). There were no malapposed
struts in BP-SES group and 14 malapposed struts in EES group (p=0.97). No difference in percent neointimal
volume (14.1±8.2% vs. 11.4±6.4%, p=0.56) was observed
