Prospective Study of Clinical and Histological Safety of Pure and Uncontaminated Canadian Oats in the Management of Celiac Disease
Bibliographic record
Abstract
BACKGROUND: Pure oats are safe for most patients with celiac disease, but concerns regarding contamination by other grains limit their consumption. The Canadian Celiac Association recently released guidelines governing the production of pure oats. The objective was to test the safety of a product manufactured under these guidelines. METHODS: Fifteen adults with established, biopsy-confirmed celiac disease of ≥ 1 year duration were challenged with 350 g/wk of pure oats for 12 weeks. Symptom scores, weight, hemoglobin, ferritin, albumin, and tissue transglutaminase (tTG) were assessed at weeks 0, 6, and 12. Duodenal biopsies were obtained before and after oat challenge and assessed based on the modified Marsh-Oberhuber score. Compliance with a gluten-free diet was monitored with random food diaries. RESULTS: Fifteen patients completed the study and were analyzed in intention-to-treat and per-protocol analyses. There were no significant changes in symptom scores, weight, hemoglobin, ferritin, or albumin during oat consumption. The tTG remained negative in all patients, and the histology scores did not significantly change during oat challenge. The only relapse occurred in a patient who became noncompliant with her gluten-free diet. CONCLUSION: The findings support the safety of pure, uncontaminated oats manufactured under Canadian Celiac Association guidelines for patients with celiac disease.

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.
