Table 6 Univariate Analysis of potential predictors of conspicuities detected in cranial ultrasounds performed in neonates without NCU admission or indication for CU (Group II)

From: Analyses of pathological cranial ultrasound findings in neonates that fall outside recent indication guidelines: results of a population-based birth cohort: survey of neonates in Pommerania (SNiP-study)

  1. 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
