(a) GSTM1_P266 methylation (%) compared between lower (n = 21) and higher (n = 22) mercury exposure groups (P= 0.04), ‘X’ indicates mean value; (b) correlation between GSTM1_P266 methylation (%) and the log of blood mercury concentrations (µg/l), (r= 0.17; P= 0.27); (c) mercury levels (µg/l) compared between women with GSTM1 null (n = 20) and reference (n = 23) genotypes (P= 0.36) and (d) GSTM1_P266 methylation (%) compared between higher and lower mercury exposure groups in women with null GSTM1 genotype (left panel; n = 11 and n = 9, respectively; P= 0.09) or reference GSTM1 genotype (right panel; n = 10 and n = 13, respectively; P= 0.50), ‘X’ indicates mean value.
