We regret that the article “Executive Summary: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines” published in the February 2012 supplement of CHEST (2012;141[2][Suppl]:7S-47S) contained an error in a dosage. The related suggestion appears on p. 35S within the second bullet under the section numbered 3.2.1-3.2.5. The original text was missing the word “twice.” The corrected text reads:
We suggest ticagrelor 90 mg twice daily plus low dose aspirin over clopidogrel 75 mg daily plus low-dose aspirin (Grade 2B).
This error also appeared twice within the article “Primary and Secondary Prevention of Cardiovascular Disease: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines” (2012;141[2][Suppl]:e637S-e668S) published in the same supplement. Both online articles have been corrected.
