| 90-Day mRS 0–1 | 20 (60.6%) | 13 (54.2%) | 0.6269 | 14 (51.9%) | 19 (63.3%) | 0.3807 |
| All-cause mortality at 90 days | 2 (6.1%) | 4 (16.7%) | 0.2275 | 3 (11.1%) | 3 (10.0%) | 1.0000 |
| Final pass mTICI ≥2b | 30 (90.9%) | 22 (91.7%) | 1.0000 | 25 (92.6%) | 27 (90.0%) | 1.0000 |
| Final pass mTICI ≥2c | 24 (72.7%) | 18 (75.0%) | 0.8474 | 18 (66.7%) | 24 (80.0%) | 0.2537 |

*For categorical variables, p values are generated using a χ2 test or a Fisher’s exact test (due to expected cell sizes<5) as appropriate.
