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 Results may not be published yet.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.

Summary

This study analyzed data from 500 Crohn's disease patients to create a tool that uses routine blood tests to predict the risk of needing intestinal surgery. The goal is to help doctors move from reacting to problems to preventing them. The model is still in early development and needs more testing before it can be used widely.

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 could lead to a simple blood-based tool that helps doctors predict when Crohn's disease patients might need surgery, allowing earlier treatment adjustments.
What could go wrong
This is a retrospective study, meaning it looks back at existing data, not a controlled trial. The model needs validation in other groups before it can be used in practice.

Who is studied

This retrospective cohort study included patients with a confirmed diagnosis of Crohn's disease (CD) at the Inflammatory Bowel Disease Center of the Sixth Affiliated Hospital of Sun Yat-sen University between January 1, 2010, and December 31, 2019. All patients had regular follow-up at this center for more than 5 years and had at least two routine blood tests available during follow-up. Data were retrospectively collected from electronic medical records, with the last follow-up date of December 31, 2026.
