Fig 1 Comparison of internal thoracic artery/saphenous vein (ITA/SV) and internal thoracic artery/radial artery (ITA/RA) survival before matching (left) and after matching (right): (A) all elderly patients, (B) septuagenarian subcohort, and (C) octogenarian subcohort. Error bars = SE. The Annals of Thoracic Surgery , DOI: ( /j.athoracsur ) Copyright © 2012 The Society of Thoracic Surgeons Terms and Conditions

Fig 2 Comparison of Kaplan-Meier mortality, internal thoracic artery/saphenous vein (ITA/SV [open symbols]) and internal thoracic artery/radial artery (ITA/RA [gray symbols]) in (A) matched patients, and in the corresponding (B) septuagenarian subcohort and (C) octogenarian subcohort. Solid and dashed lines through symbols represent biphasic model fits. (CABG = coronary artery bypass graft surgery.)

Fig 3 Relative internal thoracic artery/radial artery (ITA/RA) to internal thoracic artery/saphenous vein (ITA/SV) death hazard ratio versus time since surgery in elderly coronary artery bypass graft surgery (CABG) patients: all (solid line), septuagenarians (dashed line), and octogenarians (dash-dot line). Simulations were time-truncated based on available mortality data. The Annals of Thoracic Surgery , DOI: ( /j.athoracsur ) Copyright © 2012 The Society of Thoracic Surgeons Terms and Conditions
