GSTM1 and hydrops fetalis: A Tukey’s post hoc means separations test (p < 0.05) (α = 0.05) determined that strains Hb-HP88, Hb-HVS, SRA, SF, and Sc-Cxrd caused significant mortality at five and seven days post-topical exposure and significant mortality on day three for Sri-355 when compared to strains Sc-A11, Sc-A11, HF, and controls (Figure 1).
