Rivaroxaban for the prevention and treatment of venous thromboembolism
Bibliographic record
Abstract
Venous thromboembolism (VTE) is a common and often life-threatening cardiovascular disorder. Patients undergoing total hip replacement or total knee replacement surgery are at increased risk of VTE. In this setting, clinical practice guidelines recommend the use of low molecular weight heparins, vitamin K antagonists or fondaparinux for the prevention of VTE. However, the use of these anticoagulants is beset by practical difficulties that reduce compliance to therapy and adherence to recommended guidelines. New oral anticoagulants (OACs) that are administered in fixed doses without the need for monitoring are now being introduced to clinical practice. Rivaroxaban, dabigatran and apixaban are either approved or in advanced stages of clinical development for the prevention and/or treatment of VTE. This article provides an overview of the phase III clinical development programmes for these novel OACs, with special focus on rivaroxaban. With encouraging data already emerging, the promise of a simplified single-drug approach for VTE treatment is on the horizon.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
