Raja, MRCS, FRCS(C-Th)  The Journal of Thoracic and Cardiovascular Surgery  Volume 148, Issue 6, Pages (December 2014) DOI: /j.jtcvs Copyright © 2014 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 A, Agreement between nonparametric (black) and flexible parametric (spline, red; Weibull, dashed blue; log logistic, dashed green) survival curves in the overall study population. B, Agreement between nonparametric (black) and flexible spline parametric (red) survival curves in the bilateral internal thoracic artery (BITA) and single internal thoracic artery (SITA) groups.

4 Figure 3 Estimated survival (A and C) and hazard (B and D) functions for patients aged 69 years or younger (A and B) and patients older than 69 years (C and D) receiving bilateral internal thoracic artery grafts (BITA, blue) or single internal thoracic artery grafts (SITA, red). Estimates at means of the following covariates: New York Heart Association functional class, myocardial infarction, diabetes mellitus, chronic obstructive pulmonary disease, cerebrovascular accident, peripheral vascular disease, atrial fibrillation, left ventricular ejection fraction, cardiopulmonary bypass, body mass index, and intra-aortic balloon pump. adj, Adjusted; HR, hazard ratio; CI, confidence interval.
