Increased Levels of Endothelin-1 in Cerebrospinal Fluid Are a Marker of Poor Visual Recovery after Optic Neuritis in Multiple Sclerosis Patients

Table 1

Clinical and demographic features of the study population.

	A-MS-ON	NA-MS-ON
Sex (F); (%)	7 (63.6)	5 (100)	0.245
Mean (SD) age at study time (years)	36.7 (10.5)	40.2 (5.9)	0.495
Age range at study time (years)	20-53	35-48
Mean (SD) age of MS-ON onset (years)	35.5 (9.8)	40.0 (5.6)	0.335
Age range at MS-ON onset (years)	20-52	35-47
ON at MS onset; (%)	7 (63.6)	3 (60.0)	1.000

Fisher’s exact test and the Mann-Whitney -test were used to compare categorical and continous variables, respectively. A-MS-ON: aggressive optic neuritis in multiple sclerosis; NA-MS-ON: nonaggressive optic neuritis in multiple sclerosis (see text for definition); SD: standard deviation.
