ADIPOQ and hydrops fetalis: Adiponectin levels were not different between the HF-E and SC groups, but the differences between the HF-E group and the other HF groups were significant: +71% compared to the HF group (P<0.0001), +44% compared to the HF-A group (P<0.0001), and +32% compared to the HF-L group (P<0.001) (Table 1).
