m=months VR = Ventral roots DR = Dorsal roots

0 = none of the pathological change; 1+ = The pathological change was in <5 myelinated fibers; 2+ = The pathological change was in >5 fibers and readily detectable in all examined fields; 3+ = The pathological change were numerous in any examined field.
