Arterial grafts occluded (double-arm randomised and
observational studies)
Comparing the results of 2 randomised control
studies12,13 with a total of 189 arterial grafts
evaluated by angiographic follow up, we noted no significant difference
in the rates graft occlusion between the two groups (RR: 1.00, 95% CI:
0.59 to 1.72, p = 0.99) (Figure 4F). Only 1 observational
study15 with a total of 157 grafts assessed
angiographically showed no significant difference in graft occlusion
rates between the two groups (RR: 0.29, 95%CI: 0.07 to 1.20, p =0.09) (Figure 4F). The overall results of three studies with a total of
346 arterial grafts assessed also showed no intergroup difference in
graft occlusion rates (RR: 0.77, 95% CI: 0.47 to 1.28, p = 0.31)
(Figure 4F).
