Figure 4From: An experimental model of rhinovirus induced chronic obstructive pulmonary disease exacerbations: a pilot studyLevels of IL-6 and IL-8 in nasal lavage. (A) Time course of IL-6. (B) Time course of IL-8. (C) Mean levels of IL-6 in nasal lavage when stable and at exacerbation. There was an increase in IL-6 at exacerbation but this was not significant (p = 0.054). (D) Mean levels of IL-8 when stable and at exacerbation. There was a significant increase in IL-8 at exacerbation (p = 0.046).Back to article page
