The OSI is associated with tissue neutrophilia and steroid response in CRSwNP patients. (A) The OSI levels in sinonasal tissues of CRSwNP and CRSsNP patients and normal controls. (B) Representative histological images of HNE‐positive cells (arrow indicating neutrophils) in polyp tissue of OSIhigh and OSIlow CRSwNP patients. (C) The OSI levels in sinonasal tissues of neutrophilic and non‐neutrophilic CRSwNP patients. (D) The OSI levels in sinonasal tissues of CRSwNP patients with better or poor steroid response. CRSsNP, chronic rhinosinusitis without nasal polyps; CRSwNP, chronic rhinosinusitis with nasal polyps; Neu, neutrophilic; OSI, oxidative stress index; a p < 0.05, b p < 0.01.
