Sex (F/M) 69/56
Age (mean and range) 63.28 (32–82)
Disease duration (in months; mean and range) 11.32 (1–48)
ALSFRS-R (mean and range) 44 (35–48)

  1. sALS, sporadic amyotrophic lateral sclerosis, ALSFRS-R, revised ALS functional rating scale. Bulbar, upper limb, lower limb is a clinical classification based on involved body areas at the onset of disease. Cases with only bulbar signs or symptoms for the first three months from onset, with spinal symptoms or signs occurring later, are considered bulbar onset ALS. Cases in which any spinal symptoms or signs appeared in the first three months are considered spinal onset ALS (either upper or lower limb).
