- N (%) refers to the entire cohort, the other percentages to the respective column. The nADA and bADA measurements shown here were obtained within the present study. Non-parametric summary statistics are provided for variables that were not normally distributed. Progressive MS = patients with a primary or secondary progressive disease course, as opposed to clinically isolated syndrome and relapsing-remitting MS. The dataset contained 1.6% primary progressive, 0.6% progressive-relapsing, and 18.2% secondary progressive MS patients. The frequency of nADA did not differ between progressive (35.2%) and other (35.5%) MS patients. Patients were diagnosed using the current McDonald criteria at the time of diagnosis.
