What is the comparison of three months of anticoagulation with extended anticoagulation for a first episode of idiopathic venous thromboembolism?
The comparison of three months of anticoagulation with extended anticoagulation for a first episode of idiopathic venous thromboembolism was studied in the N Engl J Med. 1999;340:901 907 study. The results showed that extended anticoagulation was more effective than three months of anticoagulation in reducing the recurrence of venous thromboembolism.
