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 Results may not be published yet.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

Summary

This study tests whether an 8-week home-based high-intensity interval training (HIIT) program, done on a stationary bike and supervised remotely, can reduce liver fat and improve other health measures in 54 adults aged 35-65 with metabolic dysfunction-associated fatty liver disease (MAFLD). Participants will do short bursts of intense pedaling followed by easy recovery, with the workout tailored to their fitness level. The goal is to see if this time-efficient exercise is safe, feasible, and effective for managing MAFLD.

What this could mean

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

Active substance
high-intensity interval training (HIIT) on a stationary bike
What this could lead to
If it works, this could offer a time-efficient, home-based exercise option to reduce liver fat and improve metabolic health in people with MAFLD.
What could go wrong
This is a small, early-stage trial with only 54 participants and no control group for comparison. Results may not apply to everyone, and the exercise program may be too intense for some.
