N = 35

Sex, male

18 (51.43%)

66.00 (47.00–93.00)

Age at disease onseta, years

65.00 (46.00–93.00)

Disease duration, months

15.87 (5.67–29.50)

Onset region, number

 Bulbar

11 (31.43%)

 Upper limb

16 (45.71%)

 Lower limb

ALSFRS-R scoreb

39.00 (34.00–42.00)

ΔALSFRS-Rb

0.59 (0.31–1.31)

MMSEb

  1. All categorical variables are presented as n (%); All continuous variables were presented as median (IQR), except for Age at the time of the study and Age at disease onset. ΔALSFRS-R was calculated by following formula: (48-ALSFRS-R)/disease duration.
  2. a Age at the time of the study and age at disease onset are presented as the median (range); b 34 patients with ALS were included in these variables.
  3. ALSFRS-R: revised amyotrophic lateral sclerosis functional rating scale; MMSE, mini-mental state examination.
