Data given as relative parameter estimates (β), (95% confidence limits), P value. Parameter estimates, 95% CI, and SE from multivariable generalized estimating equation, controlling for age, Expanded Disability Status Scale, and disease duration. β estimates were obtained by setting the reference category to different lesion group.
