Table 3 Abnormal THRT can predict asymptomatic vasospasm development

From: Early abnormal transient hyperemic response test can predict delayed ischemic neurologic deficit in subarachnoid hemorrhage

  Vasospasm No vasospasm Total
Abnormal THRP 8 0 8
Normal THRP 0 7 7
Total 8 7 15
  1. All patients including those who developed an asymptomatic vasospasm had an abnormal THRP prior to the event (p = 0.0002, Fisher’s exact test, n = 15)
