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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 examines whether two specific ultrasound measurements—the ratio of the transverse cerebellar diameter to abdominal circumference and the ratio of mid-thigh circumference to femur length—can more accurately estimate gestational age in both healthy and growth-restricted fetuses. Researchers will compare these ratios in 100 pregnant women between 24 and 28 weeks of gestation. The goal is to improve detection of intrauterine growth restriction (IUGR), a condition where a baby does not grow as expected.

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 provide a more accurate way to estimate fetal age and detect growth problems using standard ultrasound.
What could go wrong
This is a small, early-stage observational study. The findings may not apply to all pregnancies or improve outcomes directly.
