Prevalence of self‐reported asthma (A) and burden of bronchial symptoms (B) in mSC users. A. Information on self‐reported asthma was extracted from the health profile of mSC users. B. Bronchial symptoms were assessed by VAS: “How much is shortness of breath or wheezing bothering you today?”. Data are presented as median with interquartile range. Three groups of CRS patients stratified by disease control were compared by use of Kruskal‐Wallis test and Dunn's multiple comparison test (as post hoc test). *: P < .05 compared to controlled, ****: P < .0001 compared to controlled, #: P < .01 compared to partly controlled
