The effect of timing of umbilical cord clamping on newborn anemia: implications for clinical practice in the Peruvian Amazon
Bibliographic record
Abstract
Des études ont démontré que retarder la coupure du cordon ombilical pourrait réduire les risques d'anémie infantile. Un plan d'étude pré/post a été utilisé pour déterminer l'efficacité d'une intervention visant à retarder la coupure du cordon. Des femmes ont été recrutées à l'Hôpital Iquitos (Pérou) pré- (N=112) et post-intervention (N=112). Le statut hématologique des mères a été quantifié, le moment où le cordon est coupée a été chronométré et le niveau d'hémoglobine des enfants à été mesuré. La coupure du cordon a été retardée de manière significative de 113 secondes suite à l'intervention (βajusté=113.2 secondes; 95% IC =96.6-129.9). L'anémie maternelle a été identifiée comme un facteur modifiant. Chez les enfants nés d'une mère anémique, le rapport de cotes pour l'anémie est de 0.59 pour chaque minute où la coupure du cordon est retardée. Ces résultats supportent le retardement de la coupure du cordon comme mesure pouvant réduire l'anémie infantile.

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.
