- Effective Survival [ Time Frame: through study completion, an average of 3 month ]The length of time from the date of diagnosis to patient death or tracheotomy or ventilator-assisted breathing.
- Overall Survival [ Time Frame: through study completion, an average of 3 month ]The length of time from the date of diagnosis to patient death due to any cause or the last confirmed survival.
- Rate of disease progression [ Time Frame: through study completion, an average of 3 month ]The slope of decline of the ALS Functional Rating Scale-Revised (ALSFRS-R) score from the diagnosis time to the follow-up time. ALSFRS-R values from 0 to 48 and it implies better outcome when it is higher.
- Rate of Weight decline [ Time Frame: through study completion, an average of 3 month ]The slope of decline of weight
- Rate of BMI decline [ Time Frame: through study completion, an average of 3 month ]The slope of decline of BMI
- Rate of Forced Vital Capacity (FVC) [ Time Frame: through study completion, an average of 3 month ]The slope of decline of Forced Vital Capacity (FVC) to assess the respiratory function.
