CXCL8 and cystic fibrosis: In children with CF there was no association between ASL pH and inflammatory markers in bronchoalveolar lavage fluid (BALF) from the same lobe as pH measurements (Fig. 2) by Spearman’s rank correlation test: total cell count (r = 0.04, p = 0.83), neutrophil count (r = 0.13, p = 0.53), macrophage count (r = −0.28, p = 0.18) and interleukin-8 (IL-8) (r = −0.02, p = 0.90).
