Fig 1. Results of multiple regression analysis and distribution of patients according to the CIVIL scores.

(A) Tier 1: CIVIL-AS³A²P score consisted of Age (≤40 years or ≥60 years), Stroke risk (cardiac disease history) without Seizure or psychiatric history, extreme Sugar level (≤80 or ≥400mg/dl), any Asymmetry, not Ambulating, and Pressure (SBP≤90 mmHg or ≥140mmHg). (B) Tier 2: CIVIL-MAPS included Mental change, Age (≤60 years), Pressure (SBP≥160mmHg), and no Stroke risks (history of diabetes mellitus or cardiac disease). (C) Tier 3: To identify emergent large vessel occlusion patients, GFAST score was incorporated into the CIVIL scoring system (Gaze, Face asymmetry, Arm asymmetry, Speech disturbance).
