Fig. 1.

preE subjects are divided into early preE (before 34 weeks) and late preE (after 34 weeks) groups and compared their outcomes. The placental thickness in early preE subjects was 25 mm compared to 32 mm in late preE (p = 0.05) and placental volume in early preE 296 cm³ compared to 393 cm³ (p = 0.0498). Gestational age at delivery in early preE is 32.4 weeks vs 36.8 weeks in late preE (p = 0.011). About 56% of the infants (5 out of 9) who are born to early preE are small for gestational age (SGA) and 30% of the infants (3 out of 10) who are born to late preE are SGA.
