Mean serum and CSF S100B levels in patients with cerebral vasospasm compared to patients without^*.

Samples	Mean serum S100B (μg/L)		Mean CSF S100B (μg/L)
	Cerebral vasospasm N = 5	No cerebral vasospasm N = 13	Cerebral vasospasm N = 5	No cerebral vasospasm N = 13
Baseline	0.10	0.19	23.5	29.6
Day 5	0.15	0.37	13.8	21.8
Day 6	0.21	0.15	10.1	16.3
Day 7	0.27	0.11	12.7	15.7
Day 8	0.24	0.25	12.0	12.3

*There are no statistical differences between the two groups (vasospasm vs. no vasospasm).
