Forecast horizon — calibration-scored at resolution.
By 2028, the MR CLEAN effect size (~13% absolute mRS 0–2 improvement) will be confirmed within ±3 points in pooled real-world US registries.
TL;DR · AI-generated
In patients with acute ischemic stroke caused by a proximal intracranial occlusion of the anterior circulation, intraarterial treatment administered within 6 hours after stroke onset was effective and safe.
