Fig. 4From: Sputum ACE2, TMPRSS2 and FURIN gene expression in severe neutrophilic asthmaComparison of a ACE2, b TMPRSS2 and c FURIN gene expression levels across transcriptomic-associated clusters (TACs) in sputum samples. Data shown as box-and-whisker plots showing median and interquartile range. ns not significant (p > 0.05). P values were determined by one-way ANOVA and Tukey’s multiple comparison testsBack to article page
