| Clot Characteristics | Agreement | κ | P Value |
|---|---|---|---|
| Residual flow (grades 0, 1, 2) | 86.7% | 0.66 | <.0001 |
| Clot length (≤15 vs >15 mm) | 100% | 1 | <.0001 |
| Distance from M1 MCA origin (≤10 vs >10 mm) | 100% | 1 | <.0001 |
| cirHU ≥2 vs <2) | 90% | 0.78 | <.0001 |
| Early reperfusion with IV tPA (TICI 2a–3) | 100% | 1 | <.0001 |
