Three RCTs were included in the review (n=1,468). The methodological quality of all three was found to be adequate.
EVAR was associated with statistically significantly lower perioperative mortality when compared to open repair. The fixed-effect model gave a risk ratio of 0.33 (95% CI 0.17 to 0.65, p<0.001) and the random-effects model gave a risk ratio of 0.23 (95% CI 0.12 to 0.43, p=0.0001). There was no evidence of heterogeneity between the trials.
