Additional file 1 of Sputum ACE2, TMPRSS2 and FURIN gene expression in severe neutrophilic asthma

Additional file 1: Figure S1. Comparison of sputum ACE2 gene expression levels (box-and-whisker plots showing median and interquartile range) by OCS use in asthmatics. P value was determined using unpaired t-test. Fig S2. Comparison of ACE2, TMPRSS2 and furin gene expression levels (box-and-whisker plots showing median and interquartile range) according to nasal polyps in nasal brushing. ns, not significant (p > 0.05). Table S1. Baseline characteristics of patients with asthma and healthy controls according to the site of mRNA collection. Table S2. Six asthma-associated gene sets analyzed in this study. Table S3. Absolute expression levels of ACE2, TMPRSS2 and Furin genes in different airway compartments
