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 The solid line shows the five-year survival probability and the dotted lines show the 95% confidence interval. Adjusted p = Please see the text for the risk factors included in the adjusted propensity model.
