Abstract
Please cite this paper as: Hutcheon J, Butler B, Lisonkova S, Marquette G, Mayer C, Skoll A, Joseph K. Timing of delivery for pregnancies with congenital diaphragmatic hernia. BJOG 2010;117:1658–1662. A recent report has suggested that delivery at early term ages may be associated with lower mortality among infants with congenital diaphragmatic hernia. We sought to confirm this finding by examining gestational age‐specific mortality in the USA in term infants with isolated congenital diaphragmatic hernia, delivered following the spontaneous onset of labour. In the final population of 928 infants, neonatal and infant mortality decreased with advancing gestation, from 25 and 36% at 37 weeks of gestation, respectively, to 17 and 20% at 40 weeks of gestation, respectively. Log‐binomial regression models showed that neonatal and infant mortality at 37 weeks of gestation were significantly higher than at 40 weeks. Further evidence, ideally from a randomised trial, is needed before recommendations for clinical practice on timing of delivery should be made.

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.
