171 Nippv Does not Reduce Bronchopulmonary Dysplasia (Bpd) or Death in Extremely Low Birth Weight Infants - A Randomised Trial
Bibliographic record
Abstract
Background Standard care of preterm infants includes nCPAP & NIPPV. We compared rates of BPD or death in a randomised trial of NIPPV or nCPAP. Methods Eligible infants were preterm, birth weight < 1000g; requiring either (i) non-invasive respiratory support within first seven days, “no intubation/early extubation group”, or (ii) were < 28 days at first extubation - “prior intubation”. Central block randomisation to NIPPV or nCPAP was conducted via the web. Primary outcome was a composite of death (prior to 36 weeks’ gestational age [GA]) or BPD at 36 weeks’ GA: defined as requiring ventilation; FiO2 > 30%; or positive oxygen reduction test (ORT). Sample size 1000 (β 80%; 2-tailed α 5%) to demonstrate 20% reduction in primary outcome. Results 36 international sites enrolled 1007 infants. Observed rates of BPD or death were similar in the two groups. BPD outcome, in the 21 infants with no ORT, assessed by clinical definition of oxygen at 36 weeks’ GA: no alteration in treatment differences. Conclusions In infants < 1000g NIPPV does not confer further benefit nor risk for survival free of BPD at 36 weeks’ GA compared to nCPAP.

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.
