IMS III data are only for those patients in whom CT angiography demonstrated occlusion12
*Percentages have been rounded for purposes of display.
†mRS scores are raw data derived from supplementary materials (unadjusted). The two endovascular and two standard care arms were pooled into either IA or medical treatment (regardless of penumbral profile).
