Clarification of Guideline Recommendations

In the JAMA Clinical Evidence Synopsis entitled “Aspirin Plus Clopidogrel vs Aspirin Alone for Preventing Cardiovascular Events Among Patients at High Risk for Cardiovascular Events,”¹ published in the August 14, 2018, issue of JAMA, a clarification of the guideline recommendations is being made. In the Comparison of Findings With Current Practice Guidelines section, “up to 3 months” should have been “21 days” so the revised sentence is “The use of clopidogrel combined with aspirin is recommended for up to 12 months after an acute coronary syndrome event by the joint guideline from the American College of Cardiology and the American Heart Association⁵ and by guidelines from the European Society of Cardiology^6,7 and is suggested for 21 days after a minor stroke by the joint guideline from the American Heart Association and the American Stroke Association.⁸” This article was corrected online.
