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 This study
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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 looks at 700 adults with trigeminal neuralgia who had a balloon compression procedure to relieve facial pain. Researchers will use machine learning to analyze past patient data and create a model that predicts if pain will come back. The goal is to identify key factors that influence recurrence and see if AI can outperform traditional methods.

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 tool that helps doctors predict which patients might have pain return after balloon compression, allowing for better treatment planning.
What could go wrong
This is a retrospective study using existing records, so it can't prove cause and effect. The model may not work well for all patients or in real-world settings.

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.

Who is studied

Adult patients (aged ≥ 18 years) who underwent percutaneous balloon compression (PBC) with primary trigeminal neuralgia (TN) who had their first PBC treatment at the Department of Pain Medicine, the Second Xiangya Hospital of Central South University between January 2018 and June 2025, and were willing to participate in postoperative follow-up were selected as the study subjects

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Aged ≥ 18 years. 2. Meet the diagnostic criteria for primary trigeminal neuralgia according to the International Classification of Headache Disorders, 3rd edition (ICHD-3). 3. Undergo the first PBC treatment. 4. Have complete preoperative clinical data, imaging data, and intraoperative records. 5. Have at least one postoperative follow-up record available for determining the recurrence status. Exclusion Criteria: 1. Secondary trigeminal neuralgia (e.g., caused by cerebellopontine angle tumors, multiple sclerosis, etc.). 2. Missing rate of key predictor variables (e.g., balloon shape) or outcome variables \> 15%. 3. Postoperative loss to follow-up (defined as no follow-up records available).
