Design outcomes

Primary

MeasureTime frame
To compare FeNO between patients with relapsing polychondritis and healthy volunteers, and patients with relapsing polychondritis and bronchial asthma

Secondary

MeasureTime frame
1. Correlation between FeNO2 and subject complaints (mMRC, Borg scale and VAS) 2. Correlation between FeNO and pulmonary function tests (spirometry and IOS) 3. Correlation between FeNO and eosinophil in sputum 4. Correlation between FeNO and CRP, ESR and MMP-3 5. Variation coefficient of FeNO
