The high-risk minority: undetected preterm SGA disproportionately contributes to adverse outcomes in a Chinese cohort.

Key Points

• The study aims to evaluate the impact of undetected small for gestational age (SGA) on neonatal outcomes, particularly focusing on preterm cases.
• Analyzed neonatal outcomes in a Chinese cohort.
• Compared morbidity between preterm and term undetected SGA cases.
• Examined prenatal factors influencing SGA identification.
• Undetected preterm SGA associated with higher morbidity compared to term SGA.
• Specific prenatal complications linked to poor outcomes in SGA infants.
