Errors in Abstract, Results, and End Matter

The Brief Report “Risk of QT Interval Prolongation Associated With Use of Hydroxychloroquine With or Without Concomitant Azithromycin Among Hospitalized Patients Testing Positive for Coronavirus Disease 2019 (COVID-19),”¹ published online on May 1, 2020, contained 3 errors. The first was a misstated percentage in the Abstract and Results. The phrase “3 patients (3%)” should have said “3 patients (8%).” In addition, a percentage in the Results section was missing a decimal point. The phrase “(26 patients [289%]…)” should have said “(26 patients [28.9%]…).” Finally, the Corresponding Author information for Howard S. Gold, MD, and Peter J. Zimetbaum, MD, was inadvertently omitted and has been added. The article has been corrected online.
