Summary

This study looks at whether adding a measurement of the angle between the uterus and cervix to a standard ultrasound can help predict preterm labor. Researchers will study 47 pregnant women between 24 and 34 weeks who show early signs of labor. The goal is to see if combining these two ultrasound checks improves accuracy compared to either test alone.
