What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

Summary

Researchers on Réunion Island are measuring blood sugar levels in 2,000 adults to estimate how many people have diabetes or pre-diabetes. Participants give a fasting blood sample and drink a 75g glucose solution, then give a second blood sample two hours later. The study also checks whether common risk factors like age, weight, and family history predict high blood sugar in this population. By linking to health records with consent, researchers plan to track whether early blood sugar problems lead to complications later.

What this could mean

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

Active substance
blood sugar testing with a fasting glucose sample and a 75g glucose drink
What this could lead to
If the study maps diabetes and pre-diabetes accurately, health officials could target screening and prevention programs to the people who need them most on Réunion Island.
What could go wrong
This is an observational study, so it cannot prove that any treatment works. Results from one island population may not apply elsewhere, and people who volunteer may differ from the general population.

Participants

About 2,000 people

The number the study aims to enrol. It can still change while the study runs.

Started

Apr 2025

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

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.
