21 Outcomes from randomised trials comparing EES with PES Claessen, Stone,Neth Heart J 2010;18:451-3

22 Would Syntax have been a positive trial if Xience V had been use instead of Taxus ? In SYNTAX, PCI would have been non-inferior to CABG if the 95% upper limit of the confidence interval (CI) for the difference in MACCE was below the prespecified delta of 6.6%. A hypothetical reduction of 2.2% in one-year MACCE (20 events/891 patients) would reduce the MACCE rate for PCI to 15.6%. This would have resulted in non-inferiority (absolute difference in MACCE 3.2%, 95% CI 0.0 to 6.5%). The use of EES might have led to a total reduction of approximately 81 events in the PCI group (hypothetical relative reductions of 51% in repeat intervention and 43% in MI).
