Table 1. Endovascular repair (EVAR) versus open repair (OAR) of the intact abdominal aortic aneurysm (elective procedure), results of the meta-analyses.

Authors	Data source	Results
Bulder et al., 2019 (9)	51 studies/189 022 patients	30-day mortality after EVAR with 1.16%, 95% CI [0.92; 1.39] significantly lower than after OAR with 3.27% [2.71; 3.83] (p<0.001); no difference in long-term survival up to 10 years post-operatively
Li et al., 2019 (10)	54 studies/203 246 patients	Higher long-term mortality after 5–9 years with EVAR (27.3%) versus OAR (24.7%) (p = 0.03); higher rate of reintervention (OR 2.12 [1.67; 2.69]) and higher secondary rupture rate (OR 4.84 [2.63; 8.89]) with EVAR
Antoniou et al., 2020 (11)	Synthesis of 7 randomized trials; 2 983 patients	30-day case mortality for EVAR with 1.2% significantly lower compared to OAR with 3.1% (OR 0.36 [0.20; 0.66]), p = 0.001; over the long term, aneurysm-related mortality, rates of reintervention and rupture higher after EVAR compared to OAR.
