Figure 2 [Section 3.3] Frequency of screening participants with a nodule detected on baseline LDCT scan and percentage of nodules eventually proven to be benign in LDCT studies. A, Percentage of all participants screened with LDCT imaging who had a nodule detected at baseline screening. B, Percentage of patients with a lesion identified at baseline LDCT screening that was eventually found to be benign. Cohort = single-arm cohort studies of LDCT; DANTE = Detection and Screening of Early Lung Cancer by Novel Imaging Technology and Molecular Essays Trial; DLST = Danish Lung Cancer Screening Trial; LDCT = low-dose CT; LSS = Lung Screening Study; NELSON = Dutch Belgian Randomised Lung Cancer Screening Trial; RCT = randomized controlled trial.

Figure 3 [Sections 3.3, 4.2] Frequency of patients undergoing a surgical biopsy or procedure and percentage of such surgical biopsies or procedures done for a benign lesion in LDCT studies. A, Percentage of all participants screened with LDCT imaging who underwent a surgical biopsy or procedure to evaluate a detected nodule at baseline screening. B, Percentage of patients who underwent a surgical biopsy or procedure for a lesion identified at baseline LDCT screening that was found to be benign. *Both surgical and nonsurgical (ie, needle aspiration) biopsies were reported together.
