p values comparing PSIR versus DIR (all patients): IC <0.001 and LC <0.001.
IC, intracortical grey lesion; LC, leucocortical; JC, juxtacortical white matter lesions; WM, other white matter lesions (other than JC lesions); PP, primary progressive; SP, secondary progressive; RR, relapsing remitting MS.
