Determination of iron absorption from intrinsically labeled microencapsulated ferrous fumarate (sprinkles) in infants with 'low' versus 'high' hemoglobin using a dual stable isotope method
Bibliographic record
Abstract
Microencapsulated ferrous fumarate plus vitamins A and C (Sprinkles) in powder form is a new approach for ‘home-fortification’ of complementary foods. To determine iron (Fe) absorption from Sprinkles, 44 infants with hemoglobin concentration (Hb) < 100g/L/L and 46 with Hb ≥ 100g/L were randomized to receive 30 or 45 mg of elemental Fe as 57Fe-labeled Sprinkles on 3 consecutive days. Additionally, a 58Fe tracer (0.2 mg as ferrous citrate) was infused intravenously (n = 46). Blood was drawn at baseline and 14 days later. Geometric mean Fe absorption was 8.7 and 7.0% in infants with Hb < 100g/L, and 4.6 and 4.5% in infants with Hb ≥ 100g/L for the 30 and 45 mg doses, respectively. Percent Fe absorption was significantly higher in infants with Hb <100g/L as compared to infants with Hb ≥ 100g/L (p < 0.0001), however there was no significant effect of dose (p = 0.35). Fe absorption from Sprinkles is regulated according to Fe needs.

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.
