Abstract

Background: The benefits of endovascular thrombectomy (EVT) are time dependent. Prior studies may have underestimated the magnitude of the time-benefit relation because time of onset (last known well ”LKW”) is imprecisely known, and analyses including late-arriving patients have under-representation of “fast-progressors.” Methods: Patient level data were pooled by the HERMES Investigators from all 7 RCTs of stent retriever thrombectomy devices (entirely or predominantly) versus medical therapy. Analysis was confined to early-treated patients (LKW-to-puncture≤4h). Exposures: last known well-to-door (LKWTD) time; door-to-puncture (DTP) ..
