NCT ID NCT07760753

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 Results may not be published yet.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

Summary

This study looks at how the balance of water inside and outside the body's cells changes with age. Using a simple, non-invasive device, researchers measure water levels in the whole body and in specific areas like arms and legs. The goal is to see if this balance shifts as people get older, independent of body weight, and if patterns differ between men and women.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Bioelectrical impedance analysis (a non-invasive body composition measurement)
What this could lead to
If successful, this could improve understanding of how cellular hydration changes with age, potentially informing future health monitoring or interventions.
What could go wrong
This is an observational study, so it cannot prove cause and effect. Results may not apply to people with health conditions or different body types.
