  1. a Overall adherence was defined as any follow-up CT chest following the baseline LDCT
  2. b Time to follow-up was measured among screened patients who were adherent with any follow-up CT
  3. c On-time adherence was defined as a follow-up CT within 30 days of the recommended time-frame for follow-up (13 months for Lung-RADS 1 or 2)
