Sensitivity of the Blink Reflex Test for the Different Outcomes of Brain MRI

MRI* brain (gold standard)		No. of Positive/ Total Sensitivity of BRT† (95% CI‡ )
Overall		59/65 90.8% (83.7-97.8%)
Presence of BS§ lesions	none	27/30 90.0% (79.3-100%)
	≥ 1	32/35 91.4% (82.2-100%)
Gadolinium enhancement, overall	none	40/43 93% (85.4-100%)
	in ≥ 1 lesions	19/22 86.4% (72-100%)
Gadolinium enhancement, specifically	in BS§ lesions (and hemispheric)	5/5 100%
	only in hemispheric lesions	14/17 82.4% (64.2-100%)
