Abstract
T hromboembolism involving the arterial or venous circu- lation or arising from the heart is a common cause of morbidity and mortality. Rapidly acting parenteral anticoagulants, such as heparin, are used for the prevention and initial treatment of thromboembolism and during revascularization procedures, 1 whereas the slower-acting vitamin K antagonists (VKAs) are used for long-term therapy. Development of new oral anticoagulants to replace VKAs has been slower than that of parenteral agents. Ximelagatran, an oral thrombin inhibitor, was briefly licensed in Europe but was withdrawn in 2006 because of potential hepatic toxicity. lthough this set the field back for several years, the situation has changed with the recent introduction of dabigatran etexilate, a new oral thrombin inhibitor, and rivaroxaban, an oral factor Xa (fXa) inhibitor. Licensed in Europe and Canada for prevention of venous thromboembolism (VTE) in patients undergoing hip or knee arthroplasty, dabigatran etexilate and rivaroxaban streamline out-of-hospital thromboprophylaxis because the drugs can be given once daily in fixed doses without coagulation monitoring. The greater unmet medical need, however, is to find a replacement for VKAs for long-term therapy, particularly stroke prevention in patients with atrial fibrillation (AF). The results of the Randomized Evaluation of Long-Term Anticoagulant Therapy (RE-LY) trial, which compared dabigatran etexilate with warfarin for stroke prevention in patients with AF, demonstrate that the new oral anticoagulants have the potential to be more effective and safer than VKAs.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
