Maternal Risk Factors and Short-Term Clinical Outcomes of Different Small Vulnerable Newborn (SVN) Phenotypes: A Retrospective Cohort Study of 998 Cases
This retrospective cohort study of 998 high-risk neonates demonstrates that distinct Small Vulnerable Newborn (SVN) phenotypes are driven by unique maternal risk pathways—such as inflammation for preterm/low birth weight infants and placental ischemia for the "Three-in-One" phenotype—and are associated with varying postnatal respiratory outcomes, supporting the need for phenotype-based risk stratification.
