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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study tested whether computer analysis of voice recordings can detect type 2 diabetes. Over 7,000 adults in the UK recorded themselves reading and answering questions online. A subset also provided blood samples to check accuracy. The goal is to see if voice biomarkers could become a simple, at-home screening tool for diabetes.

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 simple, non-invasive voice-based screening tool for type 2 diabetes, making early detection easier and more accessible.
What could go wrong
This is an early-stage observational study, not a treatment trial. The voice analysis may not be accurate enough for real-world screening, and results may not apply to non-English speakers or people outside the UK.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of a convenience sample of UK-based adults recruited through Prolific, an established online research platform widely used in the UK by researchers. This remote recruitment enables access to a geographically dispersed population across the UK, including individuals with known diabetes and those unaware of their metabolic health status. The online methodology reaches populations who may not engage with traditional healthcare screening, where NHS Health Check attendance is only 40.4%. The study recruits 10,000 participants for initial voice analysis, capturing diverse demographic representation to ensure model applicability across different population groups. A strategically selected subset of 1,000 participants will receive HbA1c validation testing. Existing participants from thymia's research database who consented to recontact are also eligible, having completed similar voice protocols, enriching the dataset whilst reducing participant burden.
