  1. *These potential covariates apply only to the treatment arm and do not have a control arm subset.
  2. †Atelectasis Score is a continuous variable from 0 to 100% and is defined as the % volume change in the target lobe from baseline to 180 day follow-up.
  3. ††Lobar Exclusion will be determined by the core lab radiologists and is defined as all airways into the target lobe are occluded by valves at day 180.
