MS Severity Rank Calculator

Percentiles rank the position of an individual by indicating what percent of the reference score the individual would equal or exceed.

To compute the rank of an MS patient compared to MSBase patients with similar characteristics, first select the MS course of the patient (CIS/RR onset or Progressive onset) then enter the EDSS scores at various MS durations.

The MS Severity Rank Calculator provides a general indication of disease severity and comparative outcomes of disease for people with MS, based on the disease duration time points selected. This tool is based on the cohort ranks using the large MS cohort in the MSBase Registry.
