Summary

This study gathers information from 1,200 pregnant people carrying twins that share a placenta (monochorionic twins). Researchers track complications like preterm birth and infant death to better understand these high-risk pregnancies. No new treatments are tested; the goal is to learn from real-world outcomes to guide future care.
