- FIG 1.
Decision rates in favor of EVT for different occlusion locations (A), decision rates in favor of EVT in M2 segment MCA occlusions for different geographic regions (B), for different specialties (C), and hospital settings (D). Blue dots illustrate decision rates under assumed ideal conditions and red dots decision rates under current local resources. Decision rates under current resources and assuming ideal conditions in North America in (B) were identical. Decision rates under current resources for neurosurgeons were lower than under assumed ideal conditions (C).

Decision rates in favor of EVT in patients with M2 segment MCA occlusions by survey respondents across the globe, stratified by country, under current resources (bars), and assumed ideal conditions (black dots).
