Proportions of monocyte subtypes expressing CCR5 in COPD, S & HNS. The figure shows proportions a CR14⁺⁺CD16^-, b CD14⁺CD16⁺ and c CD14^-CD16⁺⁺ monocytes from COPD, S and HNS expressing CCR5 determined by FACS. Each dot represents data from an individual patient; the bar represents the median value. The statistical significance of differences observed was determined by Kruskal-Wallis test with application of Dunn’s multiple comparisons test
