  • 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.
