Table 1. Differentiating Menière’s disease and vestibular migraine using combinations of gain deficit, gain asymmetry and occurrence of covert anti-compensatory quick eye movements (CAQEM).

	Sensitivity	Specificity	Accuracy	P-value
CAQEM	46%	81%	65%	0.01
GAIN	17%	93%	59%	0.16
ASYM	17%	81%	53%	0.87
CAQEM+GAIN	11%	100%	60%	0.02
CAQEM+ASYM	11%	98%	59%	0.10
GAIN+ASYM	11%	95%	58%	0.26
CAQEM+GAIN+ASYM	9%	100%	59%	0.05

Table 1 shows sensitivity/specificity/accuracy of distinct combinations of CAQEM occurrence, gain deficit (GAIN, vestibulo-ocular reflex gain<0.7) and gain asymmetry (ASYM, >8%) to differentiate Menière’s disease from vestibular migraine. P-values (Pearson’s chi-square test) show whether there is a relationship between the “Menière’s disease vs. vestibular migraine” differentiation and the corresponding measure (i.e., CAQEM, GAIN, ASYM and combinations). CAQEM are helpful for distinguishing Menière’s disease and vestibular migraine (see bold p-values).
