New oral anticoagulants (NOACs), including direct thrombin inhibitors (DTIs) and factor Xa (FXa) inhibitors, are emerging alternatives for prophylaxis and treatment of atrial fibrillation (AF) and venous thromboembolism (VTE).
Purpose: To compare the benefits and harms of NOACs versus warfarin for AF and VTE.
Data Sources: MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from January 2001 through July 2012; U.S. Food and Drug Administration (FDA) database for adverse event reports.
Study Selection: English-language, randomized, controlled trials (RCTs) comparing NOACs with warfarin for management of AF or VTE and observational studies and FDA reports on adverse effects.
Data Extraction: Two independent reviewers abstracted data and rated study quality and strength of evidence. Read more
