Values are n (%) or mean ± SD (weighted average) unless otherwise specified. †, P values are determined by comparison between open and endovascular groups; ‡, n = reporting frequency; §, endoleak assessed for endovascular and hybrid groups. N/A, not applicable; SCI, spinal cord ischemia; LOS, length of stay; ICU, intensive care unit; MI, myocardial infarction; CVA, cerebrovascular accident; AKI, acute kidney injury; SD, standard deviation.
