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).
