Table 5. Correlations between inflammation parameters and MMEF in different rhinitis groups.

Parameters	NAR (n=262)			AR (n=377)
	r	P		r	P
Induced sputum Eos-MMEF	0.172	0.377		0.206	<0.05^
FeNO-MMEF	0.114	0.322		0.253	0.117
Induced sputum Eos-FeNO	0.163	<0.05^		0.392	<0.01^

Data with ^{^} indicated the between-group comparison with statistical significance. MMEF, maximal mid-expiratory flow; NAR, non-allergic rhinitis; AR, allergic rhinitis; FeNO, fractional exhaled nitric oxide.
