- Data are the number of individuals (%) in each group. *Mild or significant conspicuities were compared to inconspicuous cranial ultrasounds. NCU: neonatal care unit; CU: cranial ultrasound; APGAR score: assessment score for appearance, pulse, grimace, activity, and respiration of the neonate; RDS: respiratory distress syndrome. Birth risks (based on documentation in German maternal booklet for prenatal examinations): e.g., multiple births, vaginal infections, twin births etc. P-values were derived with Fisher’s Exact Test
