Categorical variables are expressed as frequency (%), while continuous variables as mean (SD). Adjustment variables in the multivariable logistic regression were age, sex and pack year. The following LDCT scan findings were not represented in this cohort: bronchiolitis, bronchiolitiasis, tracheal deviation, pulmonary trunk ectasia, pericardium pouring, thoracic cage abnormalities and hiatal hernia
