All clinical data were collected from the patient records by the Placental Biobank of Mount Sinai Hospital, Toronto, with ethical approval from the Mount Sinai Research Ethics Board and written patient consent. Statistical differences between the groups were tested by ANOVA analysis or by Student's t test where appropriate.

AEDF, absent end‐diastolic flow; AGA, average weight for gestational age; AST, aspartate transaminase; ALT, alanine aminotransferase; dBP, diastolic blood pressure; SGA, small weight for gestational age; sBP, systolic blood pressure; REDF, reduced end‐diastolic flow.
