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.

Summary

This study looks at whether blood flow in a small fetal vein, measured by ultrasound, can predict pregnancy outcomes. Researchers will compare 160 pregnant women with and without intrauterine growth restriction (IUGR) between 24 and 37 weeks. The goal is to improve early detection of high-risk pregnancies and guide better care.

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 help doctors identify high-risk pregnancies earlier and improve monitoring for fetal health.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to direct changes in care, and results may not apply to all pregnancies.

This is an AI summary of the original study and may miss details. Read our disclaimer.
