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
