Study based on meta-analysis, including studies in the literature since 1966 that met preselected criteria, including differentiation of RRMS, enrollment of greater than 40 patients, observation > 5 years, and followup collection exceeding 80 percent.

The most important predictors were sphincter symptoms at onset and early disease course outcomes. Age at onset, sex, were weak factors.
