Direct thrombin inhibitors vs low molecular weight heparin

All‐cause Mortality events · patients with prevention of venous thromboembolism following total hip or knee replacement

Direct thrombin inhibitors probably leads to higher all‐cause Mortality events compared with low molecular weight heparins (moderate certainty).
