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

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)
