1 Lobectomy improves ventilatory function in selected patients with severe COPD1 
Robert J Korst, MD, Robert J Ginsberg, MD, Maneesh Ailawadi, MD, Manjit S Bains, MD, Robert J Downey, MD, Valerie W Rusch, MD, Diane Stover, MD  The Annals of Thoracic Surgery  Volume 66, Issue 3, Pages (September 1998) DOI: /S (98)

2 Fig 1 Relationship between the preoperative chronic obstructive pulmonary disease (COPD) index and the change in forced expiratory volume in 1 second (FEV1) after lobectomy in 32 patients. The broken, horizontal line marks zero change in FEV1, and the oblique line marks the line of best fit. The Annals of Thoracic Surgery  , DOI: ( /S (98) )

3 Fig 2 Relationship between the percent of total perfusion to the resected lobe as determined by preoperative nuclear medicine scan and the change in forced expiratory volume in 1 second (FEV1) after lobectomy. The broken, horizontal line marks zero change in FEV1, and the oblique line marks the line of best fit. The Annals of Thoracic Surgery  , DOI: ( /S (98) )
