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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study uses artificial intelligence to look at CT scans that people already had for other reasons. The goal is to create a tool that can estimate bone age and catch early signs of osteoporosis without needing extra tests or radiation. Researchers will study 3,000 adults to see how well the AI matches a person's real age and bone health.

Who is studied

This retrospective study included about 3,000 adult participants (aged over 18 years) who underwent noncontrast abdominal CT scans that fully covered the proximal femur across multiple regions in China. Participants with poor image quality, prior hip surgery or internal fixation, bone tumors, severe hip deformities, or prior proximal femur fractures were excluded. All scans were performed for non-orthopedic indications. The study was approved by the Institutional Ethics Committee (approval number: 2024PHB388-001).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged over 18 years. * Underwent routine noncontrast abdominal CT scans. * CT scans fully included the proximal femur. * Scans were performed for non-orthopedic clinical indications. * Provided necessary demographic information (e.g., age, sex). Exclusion Criteria: * CT scans with poor image quality or severe artifacts that precluded accurate analysis. * History of hip surgery or presence of internal fixation devices. * Presence of bone tumors in the proximal femur. * Severe hip deformity or prior fractures affecting the proximal femur. * Pediatric patients or pregnant individuals (if applicable).
