Figure 2. Benefit of Endovascular Recanalization According to Imaging Criteria of the Selected Endovascular Treatment (EVT) Trials.

A, Modified Rankin Scale (mRS) score of 0-2 at 3 months after stroke. B, Favorable shift in mRS scores at 3 months after stroke. P values represent the statistical significance of the effect modifications according to trial eligibility. The eligibility according to the imaging criteria of selected trials was evaluated in 127 cases for the ESCAPE (Endovascular Treatment for Small Core and Anterior Circulation Proximal Occlusion With Emphasis on Minimizing CT to Recanalization Times) trial, 150 cases for the DAWN (DWI or CTP Assessment with Clinical Mismatch in the Triage of Wake-up and Late Presenting Strokes Undergoing Neurointervention With Trevo) trial, and 109 cases for the DEFUSE 3 (Endovascular Therapy Following Imaging Evaluation for Ischemic Stroke) trial.

^aThe odds ratios (ORs) and 95% CIs of EVT were from the main model without the propensity score matching.
