INS and hydrops fetalis: Following the administration of glucose, the plasma insulin response curve in HF-SMFA group was higher than in the LF or HF-ePUFA groups, with significant differences when assessed as area-under-the-curve for plasma insulin between HF-SMFA group and the LF or HF-ePUFA groups, but not between the LF and HF-ePUFA groups (panel D).
