Outcomes of Preterm Infants with a Periventricular Venous Infarction in the Neonatal Period
Bibliographic record
Abstract
Abstract We compared the neurodevelopmental outcomes of infants with and without a periventricular venous hemorrhagic infarction (PVHI). The study was designed as a case–control study. The primary outcome measure was any score of < 85 in at least one of the cognition, language, or motor domains of the Bayley Scales of Infant and Toddler Development-3rd edition (Bayley-III) at 18 to 24 months corrected age. Of 41 infants identified, 20 index infants were matched with 40 controls for analyses. No differences in the primary outcome were noted between the two groups of infants, 52.9% with PVHI compared with 62.5% without PVHI (OR: 0.68, 95% CI: 0.21–2.13; p = 0.56). Infants with a PVHI were likely to have cerebral palsy, 85% compared with 7.5%, with the majority (70%) being ambulatory. Infants with a PVHI were developmentally similar to their preterm counterparts as it related to cognition and language.

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.
