Annual examination was defined as people receiving a follow-up examination within 11-15 mo of the initial examination. If a second examination occurred < 11 mo after baseline, it was assumed to be a part of the workup of screening-detected abnormalities. Analyses were limited to individuals with Lung Imaging Reporting and Data System categories 1 and 2 at baseline examination. Models were adjusted for sex, age, race, smoking status, ethnicity, education, insurance type, geographic region, year, and facility category. Models account for correlation among patients within facilities.
