Table 1.
Current use of disease-modifying therapies (DMTs) according to age groups based on data from the North American Research Committee on Multiple Sclerosis (NARCOMS) registry and the Multiple Sclerosis Surveillance Registry (MSSR).

The p values are reported from Chi-square tests used to assess differences in DMT use between PwMS of each age group in the two registries.
PwMS, people with multiple sclerosis.
