a
DSA imaging data were lost for two patient in the non-ICAD group, and in sub-analysis, the lost mTICI score wasn't filled with the worst value.
b
Data on the symptomatic intracranial hemorrhage within 36 h were missing for four patients in the Non-ICAD group.
c
Data on mRS at 90 days were missing for one patient in the ICAD group and four patients in the non-ICAD group.
Bold values of P indicate a statistically significant difference.
