Abstract

fetched live from OpenAlex

Around 51 million children globally are exposed to elevated levels of arsenic in drinking water However; the extent to which exposure is related to deaths from cancer at a young age is unknown. We assembled a cohort of 58,406 children aged 5–18 years from Health and Demographic Surveillance System of icddrb in Bangladesh and followed during 2003–2015. The follow-up period was 543415 person-years. We observed a significant association between childhood cancer mortality and arsenic exposure in the highest exposure tertile (HR=2.70, 95% CI =1·25–5.83). Arsenic exposure was associated with substantial increased risk of deaths at young age from cancers where child (5–11 years) had a higher risk of death compared to adolescent (12–18 years).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
