How is the MSSS calculated?

MSSS maps EDSS score to disease duration percentile from a 9892-patient reference database. Scores 0–10 rank disability relative to all MS patients with the same disease duration.

What is the difference between MSSS and EDSS?

EDSS measures absolute disability at a point in time; MSSS contextualises that disability relative to disease duration, allowing meaningful comparison between patients diagnosed at different times.
