Correlations between ACE2 gene expression and IFN response gene expression in the sinus mucosa and IT. A, ACE2 mRNA expression positively correlates with CXCL10 and CXCL11 mRNA expression in the sinus mucosa. B, ACE2 mRNA expression positively correlates with CXCL10 and CXCL11 mRNA expression in IT. C, A graphical summary of ACE2 expression in the sinonasal mucosa. Spearman rank correlation analysis was used to evaluate correlation, and significance was set at a P value of less than 0.05. ACE2, angiotensin‐converting enzyme II; IFN, interferon; CXCL, chemokine (C‐X‐C motif) ligand; CRSsNP, chronic rhinosinusitis without nasal polyps; CRSwNP, chronic rhinosinusitis with nasal polyps; IT, inferior turbinate tissues; ET, ethmoid sinus tissues; NP, nasal polyps
