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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study tested whether using a digital incentive spirometer (TryBreath) for 3 weeks could improve lung function and breathing muscle strength in 30 healthy adults aged 18 to 45. Participants used the device with a mobile app that gave real-time feedback. Researchers measured changes in lung capacity and breathing power before and after training.

What this could mean

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

Active substance
TryBreath Digital Incentive Spirometry System (device)
What this could lead to
If successful, this could point toward a simple digital tool to improve lung function in healthy people.
What could go wrong
This is a small, early study with only 30 healthy adults and no comparison group, so results may not apply to others or prove the device works better than no training.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

30 people

The number who actually took part.

May 2024

Finished

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 45 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
