Clinical Validation Data for a Novel Nasal-to-Oral Airflow Pressure Ratio

A 2026 study by Shiqi Wang provides clinical validation data for a novel nasal-to-oral airflow pressure ratio as an objective metric for nasal obstruction. The dataset includes measurements from 108 patients with self-reported nasal obstruction and 26 healthy controls. The ratio was calculated from pressure sensor recordings and correlated with patient-reported Visual Analogue Scale scores.

Use Cases

• Validating the novel nasal-to-oral airflow pressure ratio as a diagnostic metric based on the described clinical study.
• Correlating objective pressure measurements with subjective symptom scores (VAS) for nasal obstruction.
• Analyzing sex-specific differences in respiratory patterns and symptom correlation.
• Comparing the performance of this novel ratio against traditional metrics for assessing nasal obstruction.

Strengths

• Includes data from a controlled study with 108 patients and 26 healthy controls.
• The novel ratio showed a strong negative correlation with VAS scores (ρ = -0.645).
• Dataset is openly licensed under CC-BY-4.0 for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 90.6 KB, indicating limited scope.
