Figure 3From: Inflammatory thresholds and the species-specific effects of colonising bacteria in stable chronic obstructive pulmonary diseaseInflammatory thresholds of (A) CXCL8, (B) IL-1β, and (C) MPO. Low load samples were defined as a total bacterial load of ≤107.0 cfu.ml-1 (n = 32) and high load as >107.0 cfu.ml-1 (n = 32). LABC = lower airway bacterial colonisation.Back to article page
