highly significantP = 0.303
There was a highly significant difference between the clipping group and the coiling group (heterogeneity P = 0.303; I 2 = 5.8%; OR = 104.926; 95% CI: 12.931 to 851.379; P<0.001); the rate of retreatment in the clipping group was significantly lower than that in the endovascular treatment group.
