LMWH to prevent placenta‐mediated pregnancy complications: an update
Bibliographic record
Abstract
Placenta-mediated pregnancy complications, including preeclampsia, placental abruption, intrauterine growth restriction/small for gestational age and recurrent or late pregnancy loss, affect over 5% of pregnancies and can result in significant maternal and perinatal morbidity and mortality. These complications have been suggested to at least partly arise from placental insufficiency, possibly as a result of inappropriate coagulation activation. This association has led to the hypothesis that anticoagulant therapy, such as low molecular weight heparin, might reduce their occurrence. The following review will attempt to summarize the extensive research that has been performed to date exploring this hypothesis and provide guidance on the current and future role of low molecular weight heparin in women at risk for placenta-mediated pregnancy complications. A case will be made to question the widely adopted practice of prescribing low molecular weight heparin to women with prior placenta-mediated pregnancy complications and suggest possible areas for future research.

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.
