CABG–CPB, Coronary artery bypass grafting with cardiopulmonary bypass; OPCAB, off-pump coronary artery bypass.

Grafts were classified as occluded if any segment was occluded.

^†

In addition, 9 grafts in patients undergoing coronary artery bypass grafting with cardiopulmonary bypass and 4 grafts in patients undergoing off-pump coronary artery bypass could not be analyzed; 7 (6 and 1 in the coronary artery bypass grafting with cardiopulmonary bypass/off-pump coronary artery bypass groups, respectively) were pedicle internal thoracic artery grafts, 3 were radial artery (1 and 2, respectively) grafts, and 3 were saphenous vein (2 and 1, respectively) grafts.
