A randomized trial of the effect of low molecular weight heparin vs. warfarin on mortality in the long-term treatment of proximal vein thrombosis
Bibliographic record
Abstract
SummaryIt has been shown that several different low molecular weight (LMW) heparins, given by a once- or twice-daily subcutaneous injection without laboratory monitoring, are as effective or even more effective than continuous intravenous, unfractionated heparin monitored by the activated partial thromboplastin time (APTT). One such study demonstrated a statistically significant decrease in mortality over the 3 month follow-up study. This was particularly striking in patients with cancer. Based on these findings, a multicentre, randomized clinical trial has been designed to compare the effect of long-term, once-daily LMW heparin with standard treatment using heparin and warfarin to ensure that equal numbers of cancer patients are in both groups. This will demonstrate whether or not the long-term use of LMW heparin can have a significant impact on mortality in patients who have proximal venous thrombosis with or without cancer.

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.
