  • Perfect=ASPECTS of 10 and demonstrates no visualized core infarction at presentation. Non-perfect=ASPECTS <10 and demonstrates a quantifiable amount of core infarction seen at presentation.

  • All data are presented as mean (SD) or frequency (%) for continuous or categorical data, respectively. Statistical significance was assessed using Student's t test or χ2 test for continuous or categorical data, respectively.
