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

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 Results may not be published yet.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.

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 trial evaluates an active case-finding strategy to detect pulmonary tuberculosis (TB) among people with chronic obstructive pulmonary disease (COPD) in primary care clinics in Henan, China. The strategy uses computer-aided diagnosis and a rapid TB test during routine COPD visits. The study aims to see if this approach finds more TB cases than usual care and to understand how common COPD-TB comorbidity is in this population.

What this could mean

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

Active substance
an active case-finding strategy using computer-aided diagnosis and GeneXpert testing
What this could lead to
If successful, this approach could help identify tuberculosis earlier in people with COPD, potentially reducing the spread of TB and improving treatment outcomes.
What could go wrong
The trial is observational in design and focuses on a specific region in China, so results may not apply elsewhere. The screening strategy may also face practical challenges in real-world primary care settings.
