The relationship between natural log (LN) IL-13 concentrations in pg/mL and % predicted FEV1. The line was calculated using conditional standardization of the regression results for a patient with mean and modal values for the covariates in the model. The standardized line thus represents the relationship between IL-13 and FEV1 for a man, age 63, who does not currently smoke, with mean pack year smoking history of 52.5 years, who is not on statins or systemic steroids, but is on inhaled steroids (β = -0.01).
