↵a Clinical scores are presented both in total (top row) and for the upper limbs only (arm subscore, bottom row). Presented clinical scores are, from left to right: the revised ALSFRS-R at the time of MRI, ALSFRS-R progression rate at MRI, ALSFRS-R at 1 year after MRI, and MMT at MRI. The progression rate represents the decline of ALSFRS-R score per month between the first onset of symptoms and the MRI.
