Research Article: Late Loss in Lumen Diameter and Binary Restenosis for Drug-Eluting Stent Comparison

Abstract

---

Background— Published rates of coronary restenosis have fallen below 10% in drug-eluting stent trials. Early evaluations of new stents have used continuous end points that are presumed surrogates for restenosis, but the generalizability and power of such end points have not been examined systematically.
