Table 2 Multivariate Analysis of Predictors for Recurrence

From: Recurrent risk of ischemic stroke due to Vertebrobasilar Dolichoectasia

Independent predictors HR (95% CI) P value
Ischemic heart disease history 4.095 (1.221–13.740) 0.022
Basilar artery diameter ≥ 5.3 mm 4.744 (1.718–13.097) 0.003
Diffuse intracranial dolichoectasia 3.603 (1.367–9.496) 0.010
  1. Cox proportional hazards regression Forward LR method was used to examine the predictors of IS recurrence. The included covariates were conventional risk factors with a P value < 0.1 in the univariate analysis and MRI parameters such as basilar artery diameter ≥ 5.3 mm, the height of basilar artery bifurcation (score = 3), diffuse intracranial dolichoectasia, and intracranial atherosclerosis. All tests were 2-tailed, and P < 0.05 was considered significant
