Background and Purpose— Efficacy of endovascular treatment (EVT) for ischemic stroke because of large vessel occlusion may depend on patients’ age and stroke severity; we, therefore, developed a prognosis score based on these variables and examined whether EVT efficacy differs between patients with good, intermediate, or poor prognostic score. Methods— A total of 4079 patients with an acute ischemic stroke were identified from the Paris Stroke...
