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 Results may not be published yet.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

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 completed study from Seoul National University Hospital tested whether voice recordings and throat sensors can detect swallowing problems (dysphagia). Researchers collected voice samples from 259 adults before and after swallowing, comparing them with standard X-ray tests. The goal is to develop a non-invasive, machine-learning tool for diagnosis and monitoring, potentially replacing more uncomfortable procedures.

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 a simple, non-invasive voice-based test to help diagnose swallowing disorders without the need for X-ray exams.
What could go wrong
This is an early data-collection study, not a treatment trial. The voice analysis method may not prove accurate enough for clinical use.
