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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 looks at whether a painless ultrasound scan of the sciatic nerve and a blood test for a specific protein can help detect diabetic peripheral neuropathy (nerve damage) earlier than current methods. Researchers will measure nerve size and blood flow in 120 people with type 2 diabetes, grouped by nerve damage severity. The goal is to create a better diagnostic tool for early detection and management.

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 ultrasound and blood test to catch diabetic nerve damage early, before symptoms worsen.
What could go wrong
This is an early observational study with only 120 participants, so results may not apply to everyone. It aims to find patterns, not test a treatment, so no direct benefit is guaranteed.

Who can take part

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

Who is studied

This study will recruit 120 adult male and female patients diagnosed with type 2 diabetes mellitus from the Endocrinology Department of the Second Hospital of Shanxi Medical University. All participants will be stratified into groups based on diabetic peripheral neuropathy (DPN) severity assessed by the Toronto Clinical Scoring System (TCSS). Participants will include patients across the full spectrum of DPN severity, ranging from those with no or minimal neuropathy signs to those with severe clinically evident neuropathy. The study does not include a healthy non-diabetic control group. Participants will undergo a single-visit assessment including high-frequency ultrasound of the sciatic nerve and inferior gluteal artery, nerve conduction studies, and blood sample collection for serum biomarker analysis.
