Fig. 1From: Defective monocyte-derived macrophage phagocytosis is associated with exacerbation frequency in COPDStability of MDM phagocytosis to a H. influenzae and b S. pneumoniae over time. Repeat stable samples were collected over a median time of 9.5 [6.0–14.0] months. Phagocytosis of fluorescently labelled bacteria was measured after 4 h by fluorimetry. N = 36. Data show individual data points, analyzed by Wilcoxon-matched pairs testBack to article page
