Effect of Long-Term LMWH on Post-thrombotic Syndrome in Patients With Iliac/Noniliac Venous Thrombosis
Bibliographic record
Abstract
Patients with iliac deep vein thrombosis (DVT) have a poor prognosis and high incidence of postthrombotic syndrome (PTS). We evaluated the effect of low-molecular-weight heparin (LMWH; tinzaparin) versus usual care (tinzaparin plus warfarin for ≥12 weeks at home) in the development of PTS according to DVT location (iliac/noniliac) by retrospective analysis of the Home-LITE cohort (480 patients with proximal DVT). Patients with iliac DVT had an overall odds ratio of 0.53 (95% confidence interval [CI] 0.33, 0.83; P = .0079) for PTS (including ulcer data) in favor of tinzaparin. Patients with noniliac DVT had a similar odds ratio (0.79 [95% CI 0.67, 0.93], P = .0046) to that reported in the overall Home-LITE population (0.76 [95% CI 0.66, 0.89], P = .0004; including ulcer data), both in favor of tinzaparin. Long-term LMWH may be a suitable alternative for the prevention of PTS in patients with iliac DVT who are unlikely to undergo invasive thrombolysis.

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.
