Based on all-listed procedure

12,740 stays involved the insertion of both a drug-eluting and a non-drug-eluting stent. Such stays were counted once in tabulations of total stays involving a stent procedure, while in analyses of drug and non-drug-eluting stents, those stays were counted in both groups.
