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 Results may not be published yet.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.

Summary

This study checks how precise two types of bone and body scanners (DXA and pQCT) are at measuring bone density, bone structure, and body composition. Healthy adults aged 18 and older will get scanned multiple times to see how much results vary from day to day, between technicians, and between different machines. The goal is to determine the smallest change that can be reliably detected, which helps doctors make better decisions about bone health and body fat.

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 study will help doctors know how much change in bone density or body fat is real versus just measurement error, improving diagnosis and monitoring.
What could go wrong
This is an observational study focused on machine precision, not a treatment. It will not directly improve health outcomes.
