METHODS The statistical power in.clin.cal trials such as ABSORB Japan. ABSORB Chin., EVERBIO II, AIDA, an. few meta-an.lyses by the post hoc odds ratio-based sample size calculation. an. the pattern. of artery remodelin. published in.papers from ABSORB A an. B trials were evaluated. RESULTS The phen.men.l admiration.from the first ABSORB studies in.2006-2013 was replaced by the tremen.ous disappoin.men. in.2014-2017 due to reported relatively higher rates of target lesion.failure(a mean.prevalen.e of 9.16%) an. device thrombosis(2.38%) in.ran.omized con.rolled trials. Otherwise, bioresorbable vascular scaffold(BVS) performs as well as the metallic drugelutin. sten.(DES) with a tren. toward some ben.fits for cardiac mortality [risk ratio(RR), 0.58-0.94, P > 0.05]. The un.erpowered design.was con.irmed for some studies such as ABSORB Japan. ABSORB Chin., EVERBIO Ⅱ, AIDA trials, an. meta-an.lyses of Polimen., Collet, an. Mahmoud with some un.n.en.ion.l bias(judged by the asymmetrical Fun.el plot).
