ALOX15 and Nasal congestion: The level of ALOX15 mRNA was significantly correlated with tissue eosinophils (r = 0.565, P < 0.001), olfaction scores (r = 0.400, P = 0.005), total VAS scores (r = 0.383, P = 0.007), E/M ratio (r = 0.463, P = 0.001), endoscopy scores (r = 0.409, P = 0.004), and blood eosinophils (r = 0.395, P = 0.006); but not with age, tissue neutrophils, nasal obstruction scores, rhinorrhea scores, facial pain or headache scores, CT scores, or blood neutrophils (shown in Table 2).
