Level of MUC1 in the airway lumen of LTSs with and without COPD compared with HNSs
Datasets from LTSs with (LTS+; triangles) and without (LTS−; squares) COPD compared with HNSs (circles) showing (A) total level of MUC1 in unprocessed BAL samples from Material 2; (B) level of MUC1 in processed BAL samples from Material 2; (C) proportion (%) of MUC1 present in large complexes from Material 2; (D) level of MUC1 in processed BAL samples from Material 1. Open (white) symbols denote subjects with bacterial colonization whereas solid (black) symbols denote subjects without bacterial colonization according to culture of lower airway samples from Material 2. Analytical statistics are shown according to Kruskall–Wallis one-way ANOVA on ranks.
