Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
448 subjects were pre-registered through 3 Cancer Prevention Network (CPN) member organizations from 2008 to 2013.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
363 subjects were excluded from pre-assignment: 342 ineligible via bronchoscopy, 3 participant decision, 13 lab values out of range, 1 screening time line issue and 4 suspicious of cancer.
