Venous grafts occluded (double arm randomised control studies)
Analysis of the data of 2 randomised controlled studies12,13, and a total of 175 venous grafts that were angiographically assessed showed no significant intergroup difference in venous graft occlusion rates (RR: 1.347, 95% CI: 0.75 to 2.39, p = 0.33) (Figure 5).
