PROBLEM: Question: Does progression rates and sample size estimate for PPMS based on the CLIMB study population?
Answer: Our modern PPMS cohort is demographically similar to previously studied cohorts. PPMS is associated with faster disability accrual than ROMS. Current real-world observations of time to sustained progression will inform design of new clinical trials for PPMS.

SOLUTION: yes
