Idade materna e características de recém-nascidos em óbito no período neonatal, 2000 a 2009
Bibliographic record
Abstract
The aim of this study was to identify the relation between maternal age and characteristics of infants who died at the neonatal period in Londrina – PR. Retrospective ecological study using data from the Birth Certificate, Death Certificate and Infant Death Investigation Form from the Municipal Committee for Maternal Infant Mortality Prevention, from 2000 to 2009. Univariate and bivariate analysis applying Qui-square and Fisher’s exact tests were performed considering p<0.05. 60.2% were young adults, and 22.0% of those were teenagers. Maternal age was statistically significant to type of delivery (p<0.01) and not significant to gestational age, birth weight, Apgar at the first and fifth minute. 58.2% of infants were born within less than 36 weeks, 50.0% weighted less than 1500 grams and 57.7% suffered from asphyxiation in the first minute. More than 70.0% of infants died at the neonatal period. Results did not present statistically significant relation between maternal age extreme groups but to the limited biological conditions of infants which are possibly related to pregnancy and delivery.

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.
