IgE and risk of lung function decline. A Lung function trajectories in the COSYCONET cohort. Shown are relative changes in FEV1 in the 3 groups (group A: increasing FEV1; group B: stable FEV1; group C: declining FEV1). B and C Comparison of mean concentrations of total IgE (B) or allergen-specific IgE (as measured by the SX1 screening test, C) between group B (stable FEV1) and group C (declining FEV1). D Risk of declining FEV1, according to the tertiles of total IgE or allergen-specific IgE (SX1) in serum
