Table 3

	AQP4 positive	AQP4 negative	value
Relapse
Mean	5.43; (±SD 4.357)	3.17; (±SD 3.384)	0.005
EDSS
Mean	4.07; (±SD 2.867)	2.51; (±SD 2.675)	0.006
Median	3.5; (range 0.0 to 9.5)	1.0; (range 0.0 to 9.5)

AQP4 = Aquaporin 4, EDSS = Expanded Disability Status Scale, and SD = standard deviation. value < 0.05, hence, statistically significant.
