The purpose of this meta-analysis was to systematically review randomized comparative DES trials and obtain a more precise understanding of the true treatment effect of the CYPHER® Stent and the Taxus Stent than any individual trial can provide.
Stephan Winndecker, M.D. and Peter Juni, M.D. of University Hospital Bern in Switzerland conducted a thorough review of clinical results from the head-to-head trials, analyzed extended patient follow-up data and initiated an extensive review of publications and information on these trials, many of which have been published in major medical journals.
The meta-analysis of the seven head-to-head drug-eluting stent trials – TAXI, SIRTAX, ISAR DESIRE, ISAR DIABETES, REALITY, CORPAL and BASKET - demonstrated that the CYPHER® Stent more effectively reduced the need for re-treatment, target lesion revascularization, by about 30% compared to Taxus Stent-treated patients.
"The benefit of the CYPHER® Stent in reducing the need for re-treatment was observed in multiple patient and lesion types in this analysis," stated Dennis Donohoe, M.D., vice president of worldwide clinical research and regulatory affairs for Cordis Corporation. "This rigorously conducted meta analysis establishes the highest level of scientific evidence of the relative performance of these two drug-eluting stents. The CYPHER® Stent's strong clinical performance across these trials is clearly demonstrated and will be of great value to physicians and patients.
The data from the seven trials studied in this analysis have been previously presented in medical congresses or published in journals:

| BASKET | 6 months | Lancet 2005 |
| CORPAL | 13 months | ACC 2005, submitted for publication |
| ISAR-DESIRE | 12 months | JAMA 2005 |
| ISAR-DIABETES | 9 months | NEJM 2005 |
| REALITY | 9 months | ACC 2005, submitted for publication |
| SIRTAX | 12 months | NEJM 2005 |
| TAXI | 12 months | JACC 2005 |
