Figure 6. Propensity score matched comparison of total arterial revascularisation and the use of one or more saphenous vein grafts,
n = 14,355 pairs. Reproduced with permission EJCTS 2018 [42] . SVG = 0, total arterial revascularisation; SVG ≥ 1, use of one or more
saphenous vein grafts irrespective of the number of arterial grafts; KM: Kaplan-Meier; Cox: Cox proportional hazards method; HR:
hazard ratio; 95%CI: 95% confidence interval; SVG: saphenous vein graft
Figure 7. Propensity score matched comparison of total arterial revascularisation and the use of one or more saphenous vein grafts, n =
12,316 pairs. Reproduced with permission EJCTS 2018 [42] . SVG = 0, total arterial revascularisation; SVG = 1, use of one single saphenous
vein graft irrespective of the number of arterial grafts (number of arterial grafts 1.7 ± 1.1); KM: Kaplan-Meier; Cox: Cox proportional
hazards method; HR: hazard ratio; 95%CI: 95% confidence interval; SVG: saphenous vein graft
