Abstract
PURPOSE: To identify and quantify risk factors associated with preterm birth, stratified by gestational age at birth. METHODS: Three case-control analyses were done. Controls were pregnancies of > or =37 weeks of gestational age at birth. Cases were defined as: <28, 28-32, 33- <37 weeks of gestational age at birth respectively in the three case-control analyses. Women were categorized according to whether they carried single or multiple infants. RESULTS: Obstetrical conditions (placenta previa, placental abruption), and maternal hypertension were significantly associated with preterm delivery in all case-control analyses (adjusted OR between 1.34-19.56, p < 0.05). Leading risk factors for preterm delivery in singleton pregnancies were placental abruption and placenta previa (adjusted ORs 4.85 and 4.13, p < 0.05). For multiple pregnancies they were polyhydramnios and maternal hypertension (adjusted ORs 4.39 and 2.45, p < 0.05). CONCLUSIONS: Obstetrical conditions during the pregnancy and maternal hypertension are important risk factors for preterm birth.

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 it
