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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers at Renmin Hospital of Wuhan University are studying whether brown fat activity is linked to nonalcoholic fatty liver disease. They analyze stored PET/CT scans and blood samples from 96 people who had clinically indicated scans. The goal is to find blood proteins that differ across groups with high, medium, and low brown fat activity. No new treatments or scans are given.

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 researchers find blood proteins that track with brown fat activity, those proteins could become targets for future treatments or tests for fatty liver disease.
What could go wrong
This observational study cannot prove cause and effect, and it relies on existing scans and blood samples from a small group at one hospital. The findings may not apply to other populations.

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

Adults aged 18 to 80 years who had previously undergone 18F-FDG PET/CT examination for clinical purposes were recruited. Existing PET/CT imaging data were used to assess brown adipose tissue activity, and participants were categorized into high, intermediate, and low BAT activity groups according to BAT SUVmax. Peripheral blood samples and relevant clinical data were collected for analysis. No additional PET/CT examination was performed for research purposes.

Ages

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

Inclusion Criteria: * Patients who had undergone clinically indicated 18F-FDG PET/CT examination. * Willing and able to provide written informed consent and comply with the study procedures. * No long-term use of medications such as glucocorticoids or lipid-lowering drugs; no smoking or excessive alcohol consumption (alcohol intake \<20 g/day). * High BAT activity group: BAT SUVmax ≥2.0, with clear BAT activation in the cervical, shoulder, or supraclavicular regions on PET/CT. * Intermediate BAT activity group: 1.0 ≤ BAT SUVmax \<2.0. * Low BAT activity group: BAT SUVmax \<1.0 or no detectable BAT distribution on PET/CT. Exclusion Criteria: * Use of medications affecting metabolism within the previous 3 months, such as beta-blockers or thyroid hormones. * Contraindications to PET/CT examination, such as claustrophobia or contrast-agent allergy. * Pregnancy or breastfeeding.
