Overall reintervention	0.92	(0.55; 1.55)	−0.49	.6604
Open reintervention	0.33	(0.05; 2.37)	−1.79	.1706
Endovascular reintervention	2.32	(1.17; 4.61)	3.92	.0296

Note: Results of meta‐analysis for all outcomes of interest. Pooled results of 1‐year survival were reported as an HR, pooled with the inverse‐variance method, and all other outcomes were reported as RRs, pooled with the Mantel–Haenszel method. FET is providing the RR/HR for all above data.

Abbreviations: CET, conventional elephant trunk; CI, confidence interval; FET, frozen elephant trunk; HR, hazard ratio; RRs, risk ratios.
