Error in Key Points, Abstract, and Methods sections and Title

In the Original Investigation titled “Association of Ambulatory Hemodynamic Monitoring With Clinical Outcomes in a Concurrent Matched Control Analysis,”¹ published online May 15, 2019, the study type was incorrectly identified in the Key Points, Abstract, and Methods sections. Mentions have been updated from “case-control study” (in the Key Points and Abstract) and “retrospective cohort study” (in the Methods section) to “matched cohort study” (in all locations). In addition, the title has been changed to “Association of Ambulatory Hemodynamic Monitoring of Heart Failure With Clinical Outcomes in a Concurrent Matched Cohort Analysis.”
