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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 pilot study compares how well artificial intelligence (AI) and human sonographers can measure hydration status using ultrasound of the inferior vena cava. Fifty healthy adults will be scanned by both an experienced and a beginner sonographer, with and without AI assistance, before and after a fluid challenge. The goal is to see if AI can reliably assess hydration, which could simplify future monitoring.

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 show that AI can reliably measure hydration status using ultrasound, potentially leading to faster, more consistent assessments in clinical settings.
What could go wrong
This is a small pilot study in healthy volunteers, not patients. The results may not apply to sick or dehydrated individuals, and the AI may not perform as well in real-world conditions.
