The inverse correlation was shown between nNO levels and PEAC, tissue eosinophils percentage, E/M ratio in the patients of Eos CRSwNP. Correlation between nNO levels (ppb) and (a) tissue eosinophils and (b) PEAC and (c) E/M ratio. Lund-Mackay score was uncorrelated to nNO levels. Correlation between nNO levels (ppb) and (d) Lund-Mackay score. PEAC = peripheral blood eosinophil count; E/M = ratio of ethmoid sinus and maxillary sinus CT score; nNO = nasal nitric oxide, Eos CRSwNP = eosinophilic CRSwNP
