Likelihood of Stachybotyrs atra sensitization in Canadian populations
Bibliographic record
Abstract
Consecutive patients 12 years of age or older in 2007 were assessed in two separate clinics and prick tested to Stachybotrys atra (provided by Allergy Canada) in addition to the usual screen of allergens. Also noted were sensitization to mould spores in general and atopic status. Any positive skin test to any allergen would indicate atopy and any mould spore test that was positive would indicate mould sensitizatrion. 2855 patients were enrolled, 1231 in Kitchener and 1624 in Barrie. The likelihood of atopy was 50% in Kitchener and 62 % in Barrie. The likelihood of mould sensitization in the atopic population was 18% in Kitchener and 21 % in Barrie. The number of positive tests to Stachybotrys was 10 (2 true positives and 8 boarderline) in Kitchener and 11 (2 true positives and 9 borderline positives) in Barrie. This represents 0.6 % of the total population tested and 1 % of the atopic population. Stachybotrys atra has been suggested to be a major cause of mould allergy recently in North America. Sensitization does not indicate true mold allergy but is a marker for exposure in an atopic population. The extremely low level of sensitization suggests that Stachybotrys atra is not a significant cause of mould allergy in Ontario and is not required in an allergy screen.

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.
