Figure 2From: Adhesion molecules in subjects with COPD and healthy non-smokers: a cross sectional parallel group studyCorrelations between lung function and CD11b expression on sputum neutrophils. A: Relation between FEV1/FVC and CD11b expression in smokers without chronic airflow limitation. B: Relation between disease severity, assessed by FEV1 in % of predicted value, and CD11b expression.Back to article page
