| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Effects of wood smoke on airway inflammation with Advil and Otrivin: FeNO | Comparison of the different arms over the span of 5 months. | Measurement of fractional exhaled nitric oxide (FeNO). | ClinicalTrials.gov |
| Primary | Effects of wood smoke on airway inflammation with Advil and Otrivin: Cytokines and Oxylipins | Comparison of the different arms over the span of 5 months. | An inflammation matrix will be generated, including data from nasal inflammatory cytokines and oxylipins, with independent collection from each nostril. | ClinicalTrials.gov |
| Primary | Effects of wood smoke exposure on airflow and resistance in the airways with Advil and Otrivin: PNIF | Comparison of the different arms over the span of 5 months. | Measure nasal patency using peak nasal inspiratory flow (PNIF) analysis. | ClinicalTrials.gov |
| Primary | Effects of wood smoke exposure on airflow and resistance in the airways with Advil and Otrivin: Oscillometry | Comparison of the different arms over the span of 5 months. | Determine small airways function/resistance using oscillometry. | ClinicalTrials.gov |
