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)

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)

Potential predictor	All cases (n = 3696)	Cases with mild conspicuities (n = 100)	Cases with significant conspicuities (n = 17)	p value*
APGAR < 7 at > 5 min	6 (0.2)	1 (1.0)	0	0.176
birth risks	1147 (31.0)	35 (35.0)	5 (29.4)	0.671
birth weight				0.163
< 10th percentile	111 (3.0)	1 (1.0)	0
> 90th percentile	182 (4.9)	4 (4.0)	3 (17.6)
delivery mode
spontaneous	3297 (89.2)	88 (88.0)	14 (82.4)
missed	399 (10.8)	12 (12.0)	3 (17.6)
maternal chron. Disease	1154 (31.2)	38 (38.0)	5 (29.4)	0.133
RDS prophylaxis	109 (2.9)	6 (6.0)	0	0.200

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
