Clinical profile of children with cerebral palsy born term compared with late‐ and post‐term: a retrospective cohort study
Bibliographic record
Abstract
OBJECTIVE: To determine whether cerebral palsy (CP) risks factors, neurological subtype, severity and co-morbidities differ between early/full-term-born children with CP compared with those born late/post-term. DESIGN: Retrospective cohort study. SETTING: Children with CP born between 1998 and 2014, residing in Canada, and registered in the Canadian Cerebral Palsy Registry (CCPR) (n = 1691), a database with information from 15 participating centres across six Canadian provinces. POPULATION: Children with CP from the CCPR born at 37 weeks of gestation and later (n = 802). METHODS: The clinical profile of children with CP born at 37-40 weeks of gestation was compared with those born at 41 weeks and later using the Pearson chi-square test (or Fisher's exact test) for univariate analyses of categorical data. A P value <0.05 was considered significant a priori. MAIN OUTCOME MEASURES: CP neurological subtype, Gross Motor Function Classification System (GMFCS) severity, risk factors and co-morbidities. RESULTS: Neonatal encephalopathy was found in 23.9% of children with CP born early/full-term and in 33.6% of those born late/post-term (P = 0.026). Neonatal hyperbilirubinaemia was found in 10.2% of children born in the earlier period and in 2.6% of those born in the later period (P = 0.008). Apgar score at 5 minutes, but not 10 minutes, was significantly higher in the early/full-term group (9) compared with its late/post-term counterpart (7; P = 0.046). Rates of CP subtype, severity (GMFCS) and co-morbidities did not differ significantly between the two gestational periods. CONCLUSIONS: In children with CP, neonatal encephalopathy was significantly less frequent and neonatal hyperbilirubinaemia was significantly more frequent in those born early/full-term compared with their later-born counterparts. However, clinical outcomes of CP were not significantly different between these two gestational epochs. TWEETABLE ABSTRACT: Children with cerebral palsy born early/full-term have similar outcomes to those born late/post-term.

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.
