Comparison of patients treated with intracranial stents at our institution with patients in the warfarin and aspirin arms of the WASID study
| UCLA stented patients | WASID warfarin group | WASID aspirin group | |
| Rate of ischemic stroke (patients with stroke per person-year of follow-up) | 0.194 | 0.065 | 0.083 |
Note that table 2 in the WASID study does not include TIA, and so that outcome was not examined in the table above.
