Design outcomes

Primary

Measure	Time frame	Description
Changes From Baseline Smoking Behavior at 1,2,3,4,5,6 Months	baseline, 1-month, 2-month, 3-month, 4-month, 5-month, 6-month	Self-reported smoking during the last 30 days was a dichotomous variable.

Secondary

Measure	Time frame	Description
Changes From Baseline Quality of Life at 1,2,3,4,5,6 Months	baseline, 1-month, 2-month, 3-month, 4-month, 5-month, 6-month	Functional Assessment of Cancer Therapy-Lung, Version 4 (FACT-L v. 4) was a 36-item ordinal scale, five-point scale from 0 (not at all) to 4 (very much). There were 5 domains: Physical, social/family, emotional, and functional well-being; lung cancer subscale (symptoms, cognitive function, regret of smoking). Subscale scores added to obtain total score, with higher scores indicating better quality of life.
Proportion of participants with Overall Survival up to 2 years	follow up to one or two years	survival
