Design outcomes

Primary

Measure	Time frame
Study 1: the 3-4 separate subtypes of non-atopic asthma as defined by unbiased cluster analysis. Study 2: The association between level of NO in exhaled air, percentage of eosinophils in induced sputum and extent of sinus disease as assessed by CT sinus score will be investigated by correlation analyses. Study 3: Sensitivity, specificity, positive and negative predictive value of the eNose in detecting sinus disease in non-atopic asthma.	—
