The effect of short-term intensive cyclophosphamide therapy upon 21 patients with moderately advanced multiple sclerosis is compared with a non-treated control group of 21 patients retrospectively matched for global disability. The progression of the disease was evaluated by regular disability scoring, and the results were analyzed by non-parametric statistical tests. No significant differences in the progression of the disability could be detected during a follow-up period of 2 years.
