Fig. 3From: Effects of treatment changes on asthma phenotype prevalence and airway neutrophil functionSputum neutrophil functional parameters (as assessed using flow cytometry). Data represent CIT participants who produced an adequate sample for neutrophil oxidative burst (n = 7) or phagocytosis measurement (n = 16) at both visits. Groups are stratified on the basis of treatment status (sub-optimised or optimised). a – change in % sputum neutrophils undergoing oxidative burst after stimulation with PMA, b – change in % sputum neutrophils that are capable of phagocytosing fluorescent zymosan beads in culture at 37 °C, c- change in % sputum neutrophils that are capable of phagocytosing fluorescent zymosan beads in culture at 37 °C when stratified into EA/NEA. Median values are expressed at the top of each groupBack to article page
