Basic graft characteristics
There were several significant differences in terms of baseline graft characteristic between the FFR guided CABG group and the CAG guided CABG group (Table 3). In the observational study by Toth et al15 there were significantly more arterial anastomoses (P < 0.001) and significantly less venous anastomoses (P < 0.001) in the FFR group than in the CAD-guided CABG group. Also, in the randomised study by Toth et al 2019, there were significantly more venous anastomoses per patient in the CAG-guided CABG group (P=0.031).
