The percentage and number of CD163+ macrophages in BAL and induced sputum in COPD patients. The percentage (left panel) and number of CD163+ macrophages (right panel) in BAL and induced sputum between ex-smokers (open symbols) and smokers (closed symbols) with COPD. Horizontal bars represent medians. P-values are corrected for recovery of BAL fluid using multiple linear regression.
