The average ET-1 exposure rate 72 h prior and after angiography in angiographic cerebral vasospasm (CV) positive and negative patients (a) and the average ET-1 exposure rate 72 h prior and after DCI in DCI positive and negative patients (b). Independent t tests revealed significant differences (P < 0.05) in ET-1 exposure rates between CV positive and negative patients 72 h prior vasospasm and between DCI positive and negative patients 72 h prior DCI development after normalization of data by log transformation
