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 Results may not be published yet.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.

Summary

This study tested whether a noninvasive ultrasound done on the outside of the perineum (transperineal) can accurately measure cervical length in pregnant women, compared to the standard internal (endovaginal) method. Researchers enrolled 85 women in their second or third trimester who needed a cervical ultrasound. Each woman received both types of ultrasound by different operators, and the measurements were compared to see if the external method could reliably detect a short cervix, which is a risk factor for preterm labor.

What this could mean

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

Active substance
transperineal ultrasound
What this could lead to
If successful, this could offer a less invasive alternative to the standard endovaginal ultrasound for checking cervical length, making the exam more comfortable for pregnant women.
What could go wrong
This is a small, completed study (85 participants) comparing two imaging methods, not testing a treatment. The transperineal technique may not be as accurate as the gold standard in all cases.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

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

Ages

18 years and older

Sex

Female participants only

Healthy volunteers

Not accepted

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