Abstract

fetched live from OpenAlex

In this study, the authors compared thyroid function of newborns from 11 municipalities where drinking water was disinfected by chlorine dioxide (ClO2) with that of newborns from 15 municipalities using chlorine disinfection. They estimated the mean neonatal blood thyroid stimulating hormone (TSH) levels and proportion of congenital hypothyroidism cases using the results of the Quebec neonatal screening for congenital hypothyroidism for 32,978 newborns over the period 1993-1999. There was no significant increase in the TSH level and no excess of congenital hypothyroidism when all newborns exposed to ClO2 were considered. However, for newborns with low birth weight, mean TSH level was significantly higher among those exposed to ClO2 than for those in the reference group.

Teacher imitation

Not 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.
