Machine learning sifts through IBS symptoms to find hidden patient types

NCT ID NCT07809646

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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Irritable bowel syndrome looks different from person to person, and doctors usually classify it by bowel habits alone. This study asks 500 adults with a confirmed IBS diagnosis to complete a detailed online questionnaire covering symptoms, mood, diet triggers, sleep, and digital habits. Researchers then apply machine learning to look for distinct patient subgroups hidden in those answers. The goal is to understand whether these patterns could help tailor future treatments.

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 the approach works, doctors could one day sort IBS patients into more precise groups and match each group to a treatment that fits, instead of treating everyone the same way.
What could go wrong
This study only looks for patterns in survey answers, so it cannot prove that any pattern leads to better treatment. The findings may not apply to IBS patients outside this group, and machine learning patterns can be noisy or hard to reproduce.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

A convenience sample of adult patients with a physician-confirmed diagnosis of Irritable Bowel Syndrome (IBS) recruited from online health communities, clinical networks, and social media platforms. The population includes individuals across various demographic backgrounds, IBS subtypes, and symptom severity levels, who are capable of completing a digital questionnaire regarding their clinical and lifestyle characteristics.

Ages

18 to 65 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * Participants aged 18 years or older. * Formal physician-confirmed diagnosis of Irritable Bowel Syndrome (IBS). * Ability to access and complete the digital multidimensional questionnaire. * Willingness to provide digital informed consent. Exclusion Criteria: * Presence of organic gastrointestinal diseases (e.g., Inflammatory Bowel Disease, celiac disease, or colorectal cancer). * Presence of alarm/red flag symptoms (e.g., nocturnal symptoms waking the patient). * Incomplete or inconsistent questionnaire responses.
