What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are studying whether a pulmonary rehabilitation program at moderate altitude changes airway resistance in adults with COPD. Participants complete an endurance training cycle, with some sessions using extra oxygen through a nasal tube and others breathing regular room air. The team measures breathing mechanics before and after rehab using a non-invasive test called forced oscillation, and compares results between low and moderate altitude.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
pulmonary rehabilitation at moderate altitude, with some training sessions using extra oxygen
What this could lead to
If altitude-based rehabilitation changes airway resistance, it could shape how rehab programs for COPD are designed and where they are held.
What could go wrong
This is a small study of 52 people, so any changes in breathing measurements may be modest or not hold for other patients. Altitude can also affect oxygen levels, which matters for people with COPD.
