Multivariable Cox proportional hazard models of overall survival in patients meeting USPSTF screening criteria versus long-term quitters
(A) Hospital cohort. (B) Community cohort. Results are presented for unmatched and matched analyses for age at diagnosis and pack-years. Multivariable Cox proportional hazards models were used to adjust for age, sex, race, smoking status, pack-years smoked, tumour histology and stage, and treatment modalities. USPSTF=US Preventive Services Task Force.

Kernel density plots showing the balance improvement for age at diagnosis and pack-years smoked between patients meeting USPSTF screening criteria and long-term quitters
(A) Hospital cohort. (B) Community cohort. The density of the kernel density plot represents the kernel density estimate of the probability function of a variable from patients (eg, age or pack-year), which is interpreted as a probability differential. Results are presented for unmatched and matched analyses. USPSTF=US Preventive Services Task Force.
