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 Results may not be published yet.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.

Summary

This study looked at how body posture (sitting vs standing) and the type of device used (face mask vs mouthpiece) affect peak cough flow measurements in 24 healthy adults aged 20-30. Participants performed cough tests in four different setups during a single session. The goal was to see if using a face mask or allowing standing could be a reliable alternative when standard seated mouthpiece testing is not possible.

What this could mean

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

What this could lead to
If successful, this could lead to more flexible and reliable ways to measure cough strength in patients who cannot sit upright or use a mouthpiece.
What could go wrong
This is a small, early-stage study in healthy young adults only. Results may not apply to patients with lung disease or other conditions.
