What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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 looks at how body composition (like weight and fat distribution) relates to airway tone and reactivity. Researchers will use a device called an oscillometer to measure airway resistance in 100 people who are already scheduled for a methacholine challenge test. The goal is to see if body habitus is linked to abnormal airway responses, which could improve understanding of asthma and breathing problems.

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 study could help doctors better understand how body shape and size relate to airway function, potentially improving asthma diagnosis.
What could go wrong
This is an observational study with no treatment being tested, so it will not directly lead to new therapies. Results may not apply to all populations.

This is an AI summary of the original study and may miss details. Read our disclaimer.
