Figure 1. Distribution of the 90-Day Modified Rankin Scale Score (mRS) in the Different Treatment Approach Groups at the Endovascular Thrombectomy (EVT) Center.

Patients are compared by repeated imaging vs direct to angiography (DTA) approaches. The early window indicates within 6 hours or less; the late window, within 6 to 24 hours. Patients who were treated with DTA achieved higher functional independence and lower mortality rates compared with the repeated imaging group, which was consistent across time windows. Furthermore, these results were confirmed in a propensity-matched analysis of 109 pairs.
