| Variable | Antiplatelet pretreatment (n=71) | No antiplatelet pretreatment (n=146) | P value |
| Efficacy outcomes | |||
| Complete reperfusion, n (%)* | 55 (77) | 89 (61) | 0.013 |
| Three-month functional independence (mRS scores 0–2), n (%)† | 33 (50) | 64 (48) | 0.881 |
| Three-month functional outcome (mRS score), median, IQR | 3 (1–6) | 3 (1–6) | 0.792‡ |
| Safety outcomes | |||
| Symptomatic intracranial hemorrhage, n (%) | 4 (6) | 10 (7) | >0.999§ |
| Three-month mortality, n (%) | 18 (25) | 38 (26) | 0.871 |
*Modified Thrombolysis in Cerebral Infarction (mTICI) grades 2b or 3.
†Three-month mRS scores were available in 91% (n=198) of the study population.
‡Cochran–Mantel–Haenszel test.
§Fisher’s exact test.
IQR, interquartile range; mRS, modified Rankin Scale.
