Figure 2. Comparison of fetal plasma concentration of IL-6 between fetuses with anemia and those without anemia.

Figure 2

The median fetal plasma IL-6 concentration was higher in fetuses with anemia than that of those without anemia (3.74 pg/mL, interquartile range (IQR) 1.79–14.7 vs. 1.46 pg/mL, IQR 1.18–2.63; p=0.02). The interrupted line represents the cutoff value of IL-6 concentration for the diagnosis of FIRS. All fetuses with FIRS had anemia (“empty” dots).
