Table 3 Time metrics (min) for different phases of the study. P values are provided for each component. P1: P value for the pre-intervention vs Interim-intervention comparison. P2: P value for the pre-intervention vs post-intervention comparison. P3: P value for the interim-intervention vs post-intervention comparison

From: Shortening door-to-puncture time and improving patient outcome with workflow optimization in patients with acute ischemic stroke associated with large vessel occlusion
