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.

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.
