PLAUR SNPs are associated with baseline FEV ₁ and FEV ₁ /FVC. Regression analysis was used to investigate the association between PLAUR SNPs and baseline FEV₁ and FEV₁/FVC ratio using the additive, recessive or dominant models. Data represent mean ± standard error. Covariates included in the model included age, gender, height and pack years. A = Additive, R = Recessive, D = Dominant models showing p < 0.01 are presented.
