The relation between free fatty acids in CSF and mortality.

		FFA in CSF			P value
		Mean ± SD	Median	Range
Mortality	Died	0.37 ± 0.26	0.30	0.10–1.40	0.007
	Discharge	0.24 ± 0.08	0.23	0.10–0.38

The ROC curve for correlation between FFA in CSF and mortality showed a cutoff value of 0.27, specificity of 72.2%, and sensitivity of 62.9% (Figure 1 and Table 7).
