Figure 2From: Eosinophil and T cell markers predict functional decline in COPD patients Distribution of Δ % Predicted FEV1 at the 6 Month Time Point. The bar graph represents the frequency of distribution of Δ % predicted FEV1 at the six month time point. Most participants (approximately 63%) demonstrated stable disease with the % predicted FEV1 varying less than 5% from baseline. Less than 20% of participants had an absolute decline in % predicted FEV1 of 10% or greater.Back to article page
