Chorioamnionitis at birth does not increase the risk of neurodevelopmental disability in premature infants with bronchopulmonary dysplasia
Bibliographic record
Abstract
AIM: To compare preterm infants with no bronchopulmonary dysplasia (BPD), BPD with chorioamnionitis (BPDC) and BPD with no chorioamnionitis (BPDNC) for the association with neurodevelopmental disability (NDD) at three years corrected age. METHODS: Demographic and outcome data of infants with birthweight (BW) ≤1250 g born during two epochs (1995-2000 and 2002-2007 with an interim washout period of one year) were compared on the basis of whether they had BPD, chorioamnionitis or both. Any NDD was considered present if there was either mild-severe cerebral palsy (CP), cognitive delay, visual or hearing impairment. Logistic regression modelling was performed. RESULTS: Infants (n = 1009) were included into three groups - no BPD (n = 442), BPDNC (n = 437) and BPDC (n = 130). The adjusted odds ratio (aOR) of any NDD at three years in infants with BPDC versus BPDNC was 1.37; 95% CI 0.85-2.20, and for CP the aOR was 1.66; 95% CI 0.76-3.62. Infants in the BPDC group were of lower BW, gestational age and had longer length of hospital stay, duration of mechanical ventilation, more blood transfusions and sepsis compared to BPDNC and no BPD groups (all p < 0.001). CONCLUSION: Chorioamnionitis was not associated with any increase in the odds of NDD in infants with BPD at three years corrected age.

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.
