Twin pregnancy study tests if custom growth charts lead to better care

NCT ID NCT07164001

First seen Jun 26, 2026 ยท Last updated Jun 26, 2026

Summary

This study will enroll 150 pregnant individuals carrying twins to compare two ways of tracking fetal growth: the standard growth chart used for all pregnancies versus a chart designed specifically for twins. Participants will be randomly assigned to one of the two chart methods, and researchers will monitor outcomes like birth weight, timing of delivery, and newborn health. The goal is to see if the twin-specific chart helps doctors make better decisions and reduces unnecessary interventions.

What this could mean

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

What this could lead to
If successful, this study could show that using growth charts designed specifically for twins leads to more accurate monitoring and fewer unnecessary interventions during twin pregnancies.
What could go wrong
This is a relatively small, early-stage trial (150 participants) comparing two chart-reading methods, not testing a new drug or device. The results may not change standard practice if the twin-specific charts do not clearly improve outcomes.
