LDL-C was positively correlated with total cholesterol (r = 0.910; p < 0.0001) and non-HDL-C (r = 0.980; p < 0.0001), and negatively correlated with HF class (r = − 0.360; p = 0.0120), and with concentrations of IL-6 (r = − 0.312; p = 0.037) and IL-8 (r = − 0.323; p = 0.025). The gene discussed is IL6; the disease is hydrops fetalis.
