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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This study investigates whether a set of genes and proteins called the Hippo-YAP pathway, along with related microRNAs, are involved in preterm birth. Researchers analyzed blood, placenta, and uterine tissue from women who had cesarean deliveries either at full term or after spontaneous preterm labor. By comparing these samples, they hope to uncover molecular clues that could one day help predict or understand why some babies are born too early.

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 this study finds clear differences in these molecular markers, it could point toward new ways to predict or understand preterm birth.
What could go wrong
This is a small observational study that only looks at samples after delivery. It cannot prove cause and effect, and the findings may not apply to all pregnant women.
