Abstract
OBJECTIVE AND BACKGROUND: Asbestos exposure induces generation of reactive oxygen and nitrogen species. Nitric oxide is involved in asbestos-related lung toxicity in vitro and can be measured non-invasively in humans in exhaled breath. The authors hypothesized that fractional exhaled nitric oxide concentration (FENO) would be increased in subjects with asbestos-related lung disorders. METHODS: FENO was measured in 56 subjects with asbestos-related disorders (asbestosis: 12; pleural plaques: 32; asbestos-related diffuse pleural thickening: 12) and in 35 normal subjects. The authors also measured exhaled carbon monoxide, another marker of lung inflammation. RESULTS: Median (25-75 percentile) FENO was increased in subjects with asbestosis (7.9 (6.6-15.7) p.p.b.; P=0.001) and pleural plaques (6.3 (5.3-9) p.p.b.; P=0.03) compared with normal controls (4.6 (3.5-6) p.p.b.). Subjects with DPT had a median FENO of 5.6 p.p.b., similar to controls. No significant differences in exhaled carbon monoxide were observed between controls (1.0+/-0.3 p.p.m.) and subjects with asbestosis (1.3+/-0.3 p.p.m.), pleural plaques (1.2+/-0.3 p.p.m.) or diffuse pleural thickening (1.1+/-0.3 p.p.m.). CONCLUSIONS: FENO is raised in asbestosis consistent with lung inflammation, and also in pleural plaques.

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 it
