Comparison of the levels of nNO in Control, Non-Eos CRSwNP and Eos CRSwNP groups. The nNO levels of the three groups are significantly different and arranged in the following order: Control, Non-Eos CRSwNP, Eos CRSwNP. *p < 0.05, ****p < 0.0001. Eos CRSwNP = eosinophilic CRSwNP; Non-Eos CRSwNP = non eosinophilic CRSwNP; nNO = nasal nitric oxide
