Table 3 Cox regression analyses of the risk of recurrent ipsilateral ischemic stroke

From: Recurrent stroke risk is high after a single cerebrovascular event in patients with symptomatic 50-99% carotid stenosis: a cohort study

  Crude hazard ratio p-value Adjusted hazard ratio† p-value
Clinically stable 1.0 - 1.0 -
Clinically unstable 1.5 p = 0.34 1.3 p = 0.52
Clinically highly unstable 0.6 p = 0.55 0.7 p = 0.58
0 events 7 days before the presenting event 1.0 - 1.0 -
1 event 7 days before the presenting event 2.1 p = 0.07 1.9 p = 0.16
≥2 events 7 days before the presenting event 0.6 p = 0.64 0.9 p = 0.93
0 events 7 days after* the presenting event 1.0 - 1.0 -
1 event 7 days after* the presenting event 0.3 p = 0.17 0.2 p = 0.15
≥2 events 7 days after* the presenting event 1.0 p = 0.97 0.8 p = 0.78
  1. * For events after the presenting event: Only additional TIA or amaurosis fugax that occurred before CEA and before recurrent ipsilateral ischemic stroke were analyzed.
  2. † Adjusted for age, sex, degree of symptomatic carotid stenosis and type of presenting event.
