Table 5. The performances of H-FABP and S100B biomarkers at 100% sensitivity, ≤ 6 h post-trauma in mTBI subgroups; isolated brain trauma or multiple trauma patients.

	Protein	CT-, n	CT+, n	Cut-off	SE % (95% CI)	SP % (95% CI)
Isolated brain trauma	S100B	100	24	0.052	100 (100–100)	9.0 (4.0–15.0)
	H-FABP	100	24	2.62	100 (100–100)	35.0 (26.0–44.0)
Multiple trauma	S100B	39	8	0.031	100 (100–100)	5.1 (0.0–12.8)
	H-FABP	39	8	2.829	100 (100–100)	18.0 (7.7–30.8)
