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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 aims to create and test a new mathematical formula that estimates how much sodium (salt) people on peritoneal dialysis consume. The researchers will enroll 30 adults who have been on peritoneal dialysis for at least three months and have no remaining kidney function. If the equation proves accurate, it could offer a simpler way to monitor dietary sodium without relying on patient recall or food diaries.

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 equation could help doctors better manage sodium intake in peritoneal dialysis patients without needing detailed diet records.
What could go wrong
This is a small, early-stage study with only 30 participants, so the equation may not be accurate for all patients or in different settings.

This is an AI summary of the original study and may miss details. Read our disclaimer.
