  1. Analysis performed by linear mixed model. Covariates were age, time, gender, height, smoking status, pack years, age2, height2. The R2 reported for clinical covariates (no biomarkers) is given. The R2 reported for biomarkers refers to the R2 of the biomarkers(s) over clinical covariates alone. *p < 0.05 in a two-sided t-test for the null hypothesis that β = 0
