Fig 1 Unadjusted Kaplan-Meier curves depict long-term survival in patients who underwent off-pump (dotted line) and on-pump (solid line) coronary artery bypass grafting at Baylor University Medical Center (Dallas, TX) between January 1997 and December 2008. Unadjusted p = 0.012 (log-rank). The Annals of Thoracic Surgery 2011 92, 571-578DOI: (10.1016/j.athoracsur.2011.03.100) Copyright © 2011 The Society of Thoracic Surgeons Terms and Conditions
Fig 2 Adjusted proportional hazard model curves depict long-term survival in patients who underwent on-pump (solid line) and off-pump (dotted line) coronary artery bypass grafting at Baylor University Medical Center (Dallas, TX) between January 1997 and December 2008. Adjusted hazard ratio, 1.18 (95% confidence intervals, 1.02 to 1.38). Please see text for the risk factors included in the proportional hazard model.

Fig 3 Five-year adjusted survival probability, estimated with a proportional hazard model, depicting long-term survival by number of procedures performed by the surgeon in patients who underwent off-pump coronary artery bypass grafting at Baylor University Medical Center (Dallas, TX) between January 1997 and December 2008. The solid line shows the five-year survival probability and the dotted lines show the 95% confidence interval. Adjusted p = 0.774. Please see the text for the risk factors included in the adjusted propensity model.
