§, for one subject, the CT scan evaluation at round 2 was deemed suspicious (with immediate recall) even in the absence of pulmonary nodules, due to the identification of atelectasis (collapsed lung) in the scan images. LDCT, low dose computed tomography; H, high test results; M, moderate level test result; NS, non-significant level test result.
