  • Secondary analysis of the SWEDEGRAFT randomised trial

Outcomes ascertained through national population-based registries

Authors' conclusion

In this 7-year follow-up of the SWEDEGRAFT randomized clinical trial, no-touch saphenous vein harvesting was not shown to significantly reduce the composite of death from any cause, myocardial infarction, or repeat revascularization through 7 years of follow-up.
