  • Figures are numbers of patients achieving a good functional outcome at 90 days after stroke (%).

  • *This corresponds to slight or no residual disability as a result of the stroke.

  • †Value at 30 days.

  • ‡Per protocol population analysis.

  • §19/35 anterior circulation, 1/5 posterior circulation.
