  • Note:—M1 indicates the sphenoidal segment of middle cerebral artery.

  • a Results are shown as mean ± SD, median (interquartile range), or number (percentage).

  • b Not all patients had data available for ASPECTS (n = 243), minutes from last known healthy to groin puncture (n = 211), or final infarct volume (n = 217).

  • c Variables with P < .1 added to the multivariate models.
