Note:—FU indicates follow-up.
↵a Values are presented as mean ± SD for continuous variables and No. (%) for categoric variables. The denominator used for rates (%) can be smaller than the number of subjects in each group due to missing values.
↵b Compared with the pre-index procedure.
↵c All causes of deaths within 455 days were incorporated as a follow-up mRS score of 6.
↵d Technical success evaluated at the patient level.
