Oral anticoagulants for prevention of stroke in atrial fibrillation: systematic review, network meta-analysis, and cost effectiveness analysis

British Medical Journal

Dabigatran versus Warfarin for Acute Venous Thromboembolism in Elderly or Impaired Renal Function Patients: Pooled Analysis of RE-COVER and RE-COVER II

Thrombosis and Haemostasis

Pooled analysis (n=5,107) suggests that dabigatran has better efficacy than warfarin in renal impairment, probably because of an increase in the concentration of dabigatran. Incidence of major bleeding increased with increasing renal impairment for both dabigatran and warfarin.
