In the Original Investigation entitled “Development and Validation of a Prediction Rule for Benefit and Harm of Dual Antiplatelet Therapy Beyond 1 Year After Percutaneous Coronary Intervention,” published in the April 26, 2016, issue of JAMA,1 a conflict of interest disclosure needs to be updated. The disclosures for Drs Yeh and Mauri state that they have “a pending patent for development and use of the DAPT Score.” They have withdrawn this patent application since the article has been published and this disclosure has been removed from their disclosures. Also, due to an errant font, the Supplement had question marks in an eTable and an eFigure instead of the proper information. An updated Supplement has been provided. The bar graph in Figure 2 had the incorrect frequencies. This article was corrected online.
