*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).
IA, intra-arterial; IMS, Interventional Management of Stroke; MR RESCUE, Mechanical Retrieval and Recanalization of Stroke Clots Using Embolectomy.
