Please assess the completion status of the following clinical trial:

Trial Title: Prognostic Value of a Diaphragmatic Endurance Test in Patients With Amyotrophic Lateral Sclerosis

Study Design Characteristics:
- Allocation: None
- Intervention Model: None
- Observational Model: COHORT
- Primary Purpose: None
- Time Perspective: PROSPECTIVE
- Masking: None
- Phase: None
- Number of Arms: None

Eligibility Criteria:
Inclusion Criteria for Patients :~* Older than 18 years old and younger than 80 years old~* ALS patient seen during the diagnostic assessment~Inclusion Criteria for control group :~* Older than 25 years old and younger than 80 years old~* No respiratory or neurologic active pathology~Exclusion Criteria for Patients :~* Bulbar ALS (inability to perform maximal respiratory maneuvers)~* Dementia~* Respiratory failure at diagnosis (arterial carbon dioxide partial pressure (pCO2) \> 45 mmHg)~* Respiratory or neurologic active pathology~Exclusion Criteria for control group :~* Chest wall deformation with spirometric defect

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 80 Years
- Healthy Volunteers: t

Study Arms:
- Patients (Type: None): ALS patients performing measurements of maximal respiratory forces, diaphragmatic endurance during a diaphragmatic endurance test and phrenic nerve activity at the onset of the disease and repeated every 3 months up to respiratory failure or death
- Control (Type: None): Healthy controls performing measurements of maximal respiratory forces, diaphragmatic endurance during a diaphragmatic endurance test and phrenic nerve activity. This arm will enable to establish reference values of IHT

Based on this trial design, predict the completion outcome and termination type (if applicable).
