From: Defective monocyte-derived macrophage phagocytosis is associated with exacerbation frequency in COPD
Relationship between MDM phagocytosis and exacerbation frequency. a H. influenzae b S. pneumoniae showing exacerbation frequency per year as a continuous variable (n = 92). c H. influenzae d S. pneumoniae showing exacerbation status as ‘frequent exacerbator’ ≥ 2 exacerbations/year (n = 55), or infrequent exacerbator with < 2 exacerbations per year (N = 37). Data presented as median and interquartile range. *p < 0.05 Mann Whitney test
