Ticagrelor versus Clopidogrel in Symptomatic Peripheral Artery Disease
Primary resultResult — go to the resultHazard ratio 1.02 95% CI 0.92–1.13Authors' conclusion
In patients with symptomatic peripheral artery disease, ticagrelor was not shown to be superior to clopidogrel for the reduction of cardiovascular events. Major bleeding occurred at similar rates among the patients in the two trial groups.
