Figure 2 Imputed Effect of Drug-Eluting Stents in the COURAGE Trial
Imputed effect of drug-eluting stents in the COURAGE trial by which the risk ratio (RR) for drug-eluting stents (DES) versus optimal medical therapy (OMT) was imputed from the RR for bare-metal stents (BMS) versus OMT in the COURAGE trial multiplied by the RR for DES versus BMS from a meta-analysis of historical trials in the medical literature (22). PCI = percutaneous coronary intervention; PES = paclitaxal-eluting stent (Taxus, Boston Scientific, Natick, Massachusetts); SES = sirolimus eluting stent (Cypher, Cordis Corp., Miami Lakes, Florida). Squares represent mean RR, and horizontal rules represent 95% confidence interval (CI).
