Cell counts in relation to airflow obstruction in patients with asthma (n=1074)

Cells Forced expiratory volume in 1 s (FEV1)
≥80% predicted (n=693) 60%–79% predicted (n=299) <60% predicted (n=82)
Eosinophils, % (median [IQR]) 0.5 (2.3) 1.5 (7.2)* 2.2 (7.25)*
Neutrophils, % (mean ± SD) 51.6±28.6 58.5±26.9 62.7±27.4
Total cell count, ×106/g (mean ± SD) 8.9±14.1 10.9±18.0 13.1±22.9

Compared with mild asthma (FEV1 ≥80% predicted), P<0.05. IQR Interquartile range
