1 Pulmonary Function Tests Do Not Predict Pulmonary Complications After Thoracoscopic Lobectomy 
Mark F. Berry, MD, Nestor R. Villamizar-Ortiz, MD, Betty C. Tong, MD, William R. Burfeind, MD, David H. Harpole, MD, Thomas A. D'Amico, MD, Mark W. Onaitis, MD  The Annals of Thoracic Surgery  Volume 89, Issue 4, Pages (April 2010) DOI: /j.athoracsur Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Incidence of respiratory complications as a function of (A) preoperative forced expiratory volume in 1 second (FEV1) and (B) preoperative diffusion capacity to carbon monoxide (Dlco). (□ = thoracoscopy; ■ = thoracotomy.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 Regression lines showing the predicted probability of pulmonary complications as a function of (A) preoperative % predicted forced expiratory volume in 1 second (FEV1) and (B) preoperative % predicted diffusion capacity to carbon monoxide (Dlco) for patients undergoing lobectomy through thoracotomy. The shaded areas surrounding the regression line represent 95% confidence limits. The circles at the top and bottom of the plots show the actual observed occurrence (top plot line) or lack of occurrence (bottom plot line) of a pulmonary complication and the pulmonary function measurement for each patient in the study.
