Apolipoprotein E Genotype in Very Preterm Neonates with Intrauterine Growth Restriction: An Analysis of the German Neonatal Network Cohort

Table 3

Genotype distribution (frequencies) of preterm neonates subgrouped by birth weight percentile and type of pregnancy related pathology. Patients with both, “PIH/HELLP” and “IUGR/pathological Doppler ultrasound,” were grouped into the “IUGR/pathological Doppler ultrasound” subgroup.
