a
The logistic regression analyses adjusted for recommended follow-up procedures for lung biopsy, recommended CT scan at 3 months, and number of tobacco-related comorbid conditions. CI = confidence interval; CT = computed tomography; Lung-RADS® = Lung Imaging Reporting and Data System; NRT = nicotine replacement therapy; OR = odds ratio; T1 = postscreening assessment.
b
Intensive: 0-5 sessions; Minimal: 0-2 sessions.
c
Intensive: 6-8 sessions; Minimal: 3 sessions.
d
Intensive: 2-8 wk; Minimal: 2 wk.
