Cell typeCombined placebo groupsIFNβ, 2.2 μgIFNβ, 44 μg
Values are median per cent change (range).
Data represent total cell count in 18 high power fields corrected for the percentage of actual tissue in the analysed area for cellularity, CD68+ macrophages, CD55+ fibroblasts, and CD3+ lymphocytes. There were no significant differences in change between the placebo group and either IFNβ group.
IFNβ, interferon beta.
