Errors in Results

The Original Investigation entitled “Association of Aspirin Use for Primary Prevention With Cardiovascular Events and Bleeding Events: A Systematic Review and Meta-analysis,”¹ published in the January 22, 2019, print issue, included errors in the Results section because 2 studies (the Prevention of Arterial Disease and Diabetes Trial and the Thrombosis Prevention Trial) that were identified in the search and included in the meta-analysis were unintentionally omitted from the analysis for the primary composite cardiovascular outcome. The Results have been corrected and now include these studies in all other outcome analyses.
