Figure 2 Change in forced expiratory volume in 1 s (FEV1) at 3 months in patients treated with bronchoscopic lung volume reduction with endobronchial valves compared with controls who underwent sham treatment Bars are mean and 95% CIs. Red symbols represent the four patients who had collateral ventilation detected using the Chartis system and were treated with bronchoscopic lung volume reduction.
