Correlation between acoustic rhinometry and subjective nasal patency during nasal challenge test in subjects with suspected occupational rhinitis; a prospective controlled study
Bibliographic record
Abstract
OBJECTIVES: To assess the correlation between acoustic rhinometry and visual analogue scale endpoints in the context of nasal challenge with occupational agents. DESIGN: Prospective controlled study. SETTING: University teaching hospital. PARTICIPANTS: Sixty-seven subjects with a history of work-related rhinitis and asthma symptoms. MAIN OUTCOMES MEASURES: Subjects underwent nasal challenge with control and specific agent on consecutive days. Nasal congestive response to challenge was monitored by acoustic rhinometry and visual analogue scale. RESULTS: Results showed no correlation between visual analogue scale and acoustic rhinometry measurements at baseline on the control (r=-0.13, P=0.3) and active (r=0.14, P=0.2) challenge days. No correlation was found between acoustic rhinometry and visual analogue scale when analysing all measurements obtained at all times after challenge with the control and active agent (control: r=0.09, P=0.04; active: r=0.001, P=0.9). The correlation between acoustic rhinometry and visual analogue scale was good and significant (r=-0.62, P=<0.01) when the analysis was restricted to cases showing a decrease in nasal volume>40% from baseline values. CONCLUSIONS: We showed that the correlation between acoustic rhinometry and subjective nasal patency was poor on steady conditions. However, a significant correlation was observed in those cases showing a greater nasal congestive response after challenge measured by acoustic rhinometry.

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.
