Note: The results from models 1 & 2 are adjusted for T0 Readiness to Quit and time between scan and T1.

The results from models 3 & 4 are adjusted for T0 Motivation to Quit and time between scan and T1.

The results from models 1 & 3 are adjusted for T0 Perceived Risk.

The results from models 2 & 4 are adjusted for T0 Worry about Lung Cancer.

Due to associations between pack-years and the other smoking-related characteristics, all models included only pack-years.

The results from models 1 & 2 for age, pack-years, and the overall health score are reported for 10 units increase.
