Serum 25‐hydroxyvitamin D levels and self‐reported allergic rhinitis in Norwegian adults – The <scp>HUNT</scp> Study
Bibliographic record
Abstract
BACKGROUND: The role of low vitamin D status in the development of allergic rhinitis is unclear. We aimed to investigate the relationship between serum 25-hydroxyvitamin D [25(OH)D] and incidence of allergic rhinitis in adults. METHODS: The study included a random sample from an adult population who participated in the second and third surveys of the Nord-Trøndelag Health Study (HUNT) in Norway (HUNT2, 1995-1997 and HUNT3, 2006-2008). Serum 25(OH)D levels were measured in blood samples collected at baseline. Among 1351 adults who did not report allergic rhinitis at baseline, incident allergic rhinitis was identified by participant report of having or having had allergic rhinitis or hay fever at follow-up. Adjusted odds ratios (AOR) and 95% confidence intervals (CI) were calculated after adjustment for age, smoking, physical activity, socioeconomic status, family history of allergy, body mass index, and season. The analyses were stratified by sex due to its significant interaction with 25(OH)D levels (P < 0.02). RESULTS: Over an average of 11 years, 9% of men and 15% of women developed allergic rhinitis. Among men, serum 25(OH)D level <50 nM was associated with an increased risk of incident allergic rhinitis (AOR 2.55; 95% CI 1.01-6.49); each 25 nM reduction in 25(OH)D level was associated with an AOR of 1.84 (95% CI 1.18-2.87). In women, however, the association was opposite, with AOR being 0.83 (95% CI 0.66-1.05) for each 25 nM reduction in serum 25(OH)D level. CONCLUSIONS: Vitamin D appears to play different roles in the development of allergic rhinitis among men and women.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
