Rates of perfusion abnormalities in the study patients without vasospasm or with mild vasospasm (0–25% arterial diameter reduction), moderate vasospasm (25–50% reduction) and severe vasospasm (50–100% reduction).
| p < 0.0001 & | No/Mild Vasospasm (n = 39) |
Moderate Vasospasm (n = 13) |
Severe Vasospasm (n = 8) |
