Table 1. Parental and offspring characteristics of study samples. Data are given as means ± SD. I trimester samples consist of elective abortions; II trimester samples are medically induced abortions; normal term, SGA (small-for-gestational age), LGA (large-for-gestational age), PE (preeclampsia) and GD (gestational diabetes) samples represent term pregnancies. Parity, number of deliveries before current pregnancy; n.a, not available/not applicable. f, female; m, male.
