Associations between protein concentrations and overall mortality after lung cancer by smoking status, among 986 lung cancer patients recruited from central and eastern Europe. Model 1: adjusted for age at diagnosis and sex; model 2: model 1 + education (elementary, high school, university and above), alcohol intake (never, ever), and histology (adenocarcinoma and squamous cell carcinoma); model 3: model 2 + stage (continuous). Models for ever smokers were weighted by smoking prevalence from the full cohort. ENT significant: ENT statistical significance. Nominally significant: P<0.05. SD, standard deviation; ENT, effective-number-of-tests.
