Table 3 The number of inflammatory cells in bronchial biopsies and induced sputum of COPD patients

From: Multidrug resistance-associated protein-1 (MRP1) genetic variants, MRP1 protein levels and severity of COPD

Bronchial biopsies Absolute numbers per 0.1 mm2 sub-epithelial area  
CD3 123.5 (69.2 - 182.5)  
CD4 48.0 (27.7 - 72.0)  
CD8 21.5 (11.0 - 37.2)  
Plasma cells 8.5 (3.5 - 14.5)  
Mast cells 26.5 (19.0 - 34.5)  
Macrophages 8.5 (4.5 - 13.0)  
Neutrophils 4.0 (2.0 - 8.4)  
Eosinophils 1.5 (0.5 - 4.2)  
Induced sputum Absolute numbers (104/ml) Percentage (%)
Total cell count* 139.7 (77.9 - 311.3)  
Neutrophils 101.6 (46.8 - 228.5) 72.8 (59.9 - 81.7)
Macrophages 31.1 (17.9 - 61.1) 22.1 (14.8 - 33.2)
Eosinophils 1.3 (0.4 - 4.5) 1.1 (0.3 - 2.2)
Lymphocytes 2.2 (1.1 - 6.8) 1.7 (1.2 - 2.3)
Epithelial cells 1.4 (0.6 - 3.4) 1.0 (0.3 - 2.3)
  1. Data are presented as median (25th - 75th percentile)
  2. *Total cell count refers to the number of non-squamous cells in induced sputum
