CE, cholesteryl ester; Cer, ceramides; IUGR, intrauterine growth restriction; PC, phosphatidylcholine; PE, phosphatidylethanolamine; PET, preeclampsia; PL, phospholipid; PS, phosphatidylserine; SM, sphingomyelin; TAG, triacylglycerol.
Values are mean (SD).
ANOVA was used to test for differences among groups (*on log transformed data). Different superscript numbers indicate differences between individual groups using post hoc Tukey test. Significance level P<0.05.
