Figure 1.
IST-3 (Third International Stroke Trial), ordinal regression analyses, of the effect of alteplase treatment on outcome (Oxford Handicap Scale [OHS] as the dependent variable) in patients with more vs less normal results by different angiography features. Results represent odds ratio of better (right of vertical line) or worse (left of line) 6-month outcome with alteplase. Adjusted for age, time from stroke onset to scan, and stroke severity (National Institutes of Health Stroke Scale). ICA indicates internal carotid artery; MCA, middle cerebral artery; and TICI, Thrombolysis in Cerebral Infarction.
