From: Long-term outcome of vertebral artery origin stenosis in patients with acute ischemic stroke
 | Annual event rate, per 100 patient-years units (95% CI) | P-value | |
---|---|---|---|
 | Vertebral artery origin stenosis (n = 137) | Acute lacunar infarcts (n = 169) | |
All stroke | 4.86 (2.93–8.06) | 3.38 (1.41–8.13) | 0.486 |
Unstable angina/myocardial infarction | 1.30 (0.49–3.45) | 2.71 (1.02–7.21) | 0.293 |
Vascular death | 1.30 (0.49–3.45) | 1.35 (0.34–5.41) | 0.960 |
Composite cardiovascular outcome | 6.80 (4.43–10.43) | 6.77 (3.64–12.58) | 0.990 |
