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 This study
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 Results may not be published yet.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.

Summary

Researchers at Assiut University Hospitals are following 310 critically ill adults admitted to intensive care to see how many develop gastrointestinal bleeding at least 24 hours after arrival. The study measures bleeding rates, identifies which clinical, laboratory, and treatment factors raise the risk, and tracks outcomes such as ICU length of stay, blood transfusions, and death. Participants receive standard ICU care; researchers observe and record rather than test a new treatment.

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 researchers map which ICU patients face the highest risk of gastrointestinal bleeding, doctors could target monitoring and preventive care at those patients first.
What could go wrong
This is an observational study, so it can show patterns and links but cannot prove that any single factor causes bleeding. Findings from one hospital system may not apply everywhere.
