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 2010 89, 1044-1052DOI: (10.1016/j.athoracsur.2009.12.065) Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions
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.
