Correlation between acoustic rhinometry and subjective nasal patency during nasal challenge test in subjects with
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.

Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
