The Use of Iron-fortified Wheat Flour to Reduce Anemia Among the Estate Population in Sri Lanka
Bibliographic record
Abstract
The use of flour fortified with 66 mg/kg of electrolytic or reduced iron to reduce the prevalence of anemia was determined in a two-year, double-blind, controlled trial. The trial was conducted in Sri Lanka among preschoolers between 9 and 71 months old, primary schoolers 6 to 11 years old, and nonpregnant women. At baseline, 18.4% of the preschoolers had low hemoglobin (Hb) concentrations. Neither electrolytic nor reduced iron had an effect on Hb concentration among preschoolers. Only 7% of the primary schoolers were anemic at the start of the trial and, again, fortification had no effect on Hb concentration. Twenty-nine percent of women had a low Hb at outset and there was no evidence that fortification had an effect on Hb in this group. The findings from this study suggest that fortification of flour with electrolytic iron or reduced iron was not beneficial in reducing anemia in this population. This was probably due to the low prevalence of anemia and low bioavailability of the fortificant iron. Fortification with either iron fortificant was acceptable.

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.
