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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are following 480 adults with severe obesity in Guadeloupe and French Polynesia for five years. The study checks whether having metabolic syndrome, a cluster of conditions like high blood pressure and high blood sugar, raises the risk of chronic kidney disease, heart problems, diabetes, and death. The team also looks at gene variants tied to belly fat and kidney disease to see how they relate to these outcomes.

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 the study finds links between metabolic syndrome, gene variants, and kidney or heart complications, it could help doctors identify which people with severe obesity face the highest risk and guide earlier monitoring.
What could go wrong
This is an observational study, so it can show associations but cannot prove cause and effect. Five years of follow-up may miss slower changes, and findings in Caribbean and Polynesian populations may not apply to other groups.
