Table 1. Clinical and demographic characteristics of clinically defined multiple sclerosis (MS) patients.

	Whole MS no = 65	MS relapsing-remitting no = 35	MS secondary progressive no = 20	MS primary progressive no = 10
Age (years)	41 (34 to 48)	35 (29 to 41)	45 (42 to 52)	58 (46 to 60)
Sex: percentage male, male/female	46%, 30/35	46%, 16/19	45%, 9/11	50%, 5/5
EDSS	2.5 (1 to 5)	1.5 (0.5 to 2)	5 (3.5 to 6.5)	4.3 (3 to 6.5)
Disease duration (years)	6 (3 to 13)	4 (1 to 7)	13 (6 to 21)	10 (5 to 14)
HLA2 (DR15) haplotype carriers (C)+%+/tot	54% 15/28	71% 10/14	27% 3/11	67% 2/3
Cerebrospinal fluid oligoclonal bands+%+/tot	91% 40/44	86% 19/22	100% 17/17	80% 4/5
Compliance with at least three of four MRI revised McDonald criteria%+/tot	100% 65/65	100% 35/35	100% 20/20	100% 10/10

No significant differences were found among MS subgroups for age, expanded disability disease score (EDSS), or disease duration (ANOVA). HLA2 (DR15) genetic analysis was available in 28/65 patients, and cerebrospinal fluid in 44/65.
