  1. *N = 34 stable COPD subjects, 16 rapid COPD subjects and 11 normal controls
  2. Data is reported as mean ± standard error of measurement
  3. The standard error of measurement is in parentheses
  4. Plasma cytokine levels were measured as above in stable COPD participants (n = 17) and COPD participants who demonstrated rapid decline in the first six months of the trial (n = 10). For IL-2, IL-2R and Eotaxin-1 plasma levels were determined in an additional 6 rapid decliner and 17 stable COPD subjects. IL-2 was the one cytokine that was significantly increased in stable COPD subjects compared to rapid decliners (indicated in bold, p < 0.05). Parentheses indicate standard error of measurement.
