Table 6 Annual event rate of outcomes during follow–up of patients with vertebral artery origin stenosis or acute lacunar infarcts

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
