After examining 105 patients with deep venous thrombosis (DVT) or pulmonary embolism (PE) during pregnancy or postpartum, the authors estimated that the incidence of DVT during pregnancy remained essentially unchanged over the 30-year period of study and that the incidence of postpartum DVT declined. The authors speculated that early mobilization and shorter hospitalization after delivery may have contributed to this result. This apparently advantageous observation, based on a limited database, may cause physicians to become complacent.We reported ...References1.

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.
