Independent predictors of sputum eosinophilia and sputum neutrophilia/sputum neutrophilia

	Parameter	Β	SE	OR	95% CI	p value
Sputum eosinophilia	Blood eosinophil percentage, %	0.814	0.201	2.258	1.523–3.347	< 0.001
	ACT	− 0.426	0.178	0.653	0.463–0.930	0.018
Sputum neutrophilia	Blood neutrophil percentage, %	0.706	0.247	2.026	1.249–3.287	0.004
	Age	0.989	0.357	2.688	1.335–5.414	0.006

Sputum eosinophilia is defined as sputum eosinophil proportion ≥ 3%. Sputum neutrophilia is defined as sputum neutrophil proportion ≥ 61%
