“…Baseline demographic and clinical variables, including age, sex, ethnicity, BMI, smoking history, were collected prospectively as part of the CTLS program and stored in a centralized data repository as previously described [ 21 , 22 ]. Additional clinical variables, including cancer, mortality, cause of death, date of pulmonary referral, reason for pulmonary referral, and ILD diagnosis, not already available in this data repository, were collected retrospectively by manual review of the electronic medical record or pulled directly from the EMR and stored utilizing a custom-designed database (FileMaker ProVersion 11; Filemaker Inc, Santa Clara, California).…”

“…The current U.S. national implementation of LCS uses thoracic CT to evaluate for lung cancer, but the acquired CT scan will be routinely evaluated for emphysema ( 28 ). Generally, the acquired LCS CT imaging data is analyzed for emphysema because of medical legal concerns with missing important diagnoses.…”

“…The prevalence of emphysema detected by CT in lung screening cohorts was described in 22 papers (including cohort and case–control studies) [ 14 , 26–46 ]. The prevalence of emphysema detected in lung screening cohorts varied between 2.9% and 57% [ 36 , 46 ]. The wide variation in prevalence can be explained by differing inclusion criteria, CT scanning parameters, and methodology for assessing emphysema on CT (qualitative, semi-quantitative, quantitative).…”
