Note:—mTICI indicates modified TICI.
↵a Reported as median (interquartile range) unless otherwise noted.
↵b Mann-Whitney U test.
↵c Obtained from the systolic component of the lowest observed MAP prior to mTICI 2b/3 reperfusion.
↵d Calculated as the baseline pressure minus the lowest pressure before mTICI 2b/3.
↵e Calculated as the absolute pressure drop divided by the baseline pressure.
