Differential cell count percentages

Sample Type	PMN	MAC	Eos	Lym	Bec
IS, %	29.6 (8.3–67.8)	70.1 (30.9–91.7)	0.3 (0.0–2.6)	0.0 (0.0–0.0)	0.1 (0.0–0.7)
BAL, %	2.9 (0–8)	96.8 (91.2–100)	0.2 (0.0–1.0)	0.1 (0.0–1.0)	0.1 (0–0.9)
BF, %*	12.3 (6.0–17.0)	84.0 (80.0–88.0)	0.0 (0.0–0.0)	0.0 (0.0–0.0)	3.67 (2–6)

Data are means (range). IS, n = 16; BAL, n = 20. BAL, bronchoalveolar lavage; BF, bronchial fraction; Bec, bronchial epithelial cells; Eos, Eosinophils; IS, induced sputum; Lym, lymphocytes; MAC, macrophages.

^*For BF samples, differentials were conducted on separate samples (n = 3) than those run in experimental procedures because of limited sample size.
