Demographic and clinical characteristics of relapsing–remitting multiple sclerosis (RR-MS) patients

Number of patients (Female/male)	Age (years)	Relapse rate previous 3 years	Relapse rate end of study	Basal EDSS
19F/7M	34·5 ± 10·6 (18–58)	0·79 ± 0·29 (0·3–1·3)	0·37 ± 0·68* (0–1)	1·66 ± 1·53 (0–5)

P-values < 0·05 (*) were considered significant between groups. The relapse rate changed significantly from 0·79 ± 0·29 (relapse rate previous 3 years) to 0·37 ± 0·68 (relapse rate at end of study). Expanded Disability Status Scale (EDSS) before therapy (basal EDSS) and EDSS after therapy with interferon (IFN)-β (EDSS end of the study). Data are expressed as the means ± standard deviation (range).
