Cellular profiles in bronchoalveolar lavage fluid (BALF) in idiopathic pulmonary fibrosis (IPF) patients and healthy controls

	IPF patients	Healthy controls
	n = 54	n = 36
Cellular profiles in BALF (median, IQR)

Macrophages (×106)	17·1 (12·7–25·2)*	6·4 (6·1–18·8)
Lymphocytes (×106)	1·6 (0·6–3·6)*	0·9 (0·4–1·3)
