Abbreviation for Extended Prophylaxis Comparing Low Molecular Weight Heparin to Aspirin in Total Hip Arthroplasty 

A multicentre* randomised trial of non-inferiority design that assessed the differences between aspirin and dalteparin in preventing venous thromboembolism in patients who had undergone hip replacement.

Conclusion Aspirin was noninferior and, given its lower cost and greater convenience, should be regarded as a reasonable alternative to dalteparin for extended thromboprophylaxis after hip replacement.
