TABLE 2.

The percentage of inflammatory subtypes of bronchitis in stable and exacerbated airway diseases

Physician diagnosis	Stable disease						Exacerbated disease
	Total tests, n	Inflammatory subtypes of bronchitis, %					Total tests, n	Inflammatory subtypes of bronchitis, %
		EB	NB	EBNB	Trivial NB	Normal cell counts		EB	NB	EBNB	Trivial NB	Normal cell counts
Asthma	664	36	14	6	16	28	115	35	21	13	16	15
COPD	529	18	34	7	30	11	171	18	46	8	18	10
Asthma and COPD	175	35	19	10	21	15	60	24	33	12	24	7
Chronic cough	510	19	25	5	24	27	95	14	37	13	23	13
Bronchiectasis	575	8	51	18	17	6	54	6	66	17	11	0

The total number of tests for a disease category (example, for asthma: 664+115=779) is less than the total number of patients in Table 1 because Table 2 includes data only from patients in whom sputum collection was successful. COPD Chronic obstructive pulmonary disease; EB Eosinophilic bronchitis; EBNB Combined eosinophilic and neutrophilic bronchitis; NB Neutrophilic bronchitis
