Assessment of Definitions of Sustained Disease Progression in Relapsing-Remitting Multiple Sclerosis

Figure 3

Time to sustained progression for functional system score definitions. Each graph represents a different definition of sustained progression: top row (from left to right)—increase on pyramidal subscale (D5), increase on cerebellar subscale (D6), increase on brainstem subscale (D7), increase on sensory subscale (D8); middle row (from left to right)—increase on bowel-bladder subscale (D9), increase on mental subscale (D10), increase on visual subscale (D11), increase on any subscale (D12); bottom row (from left to right)—increase in first subscale (D13), increase of 2 in the sum of the subscales (D14), increase of 3 in the sum of the subscales (D15).
