Fig. 2From: Long-term environmental metal exposure is associated with hypomethylation of CpG sites in NFKB1 and other genes related to oncogenesisDifferentially methylated positions in association with the plasma levels of chemical elements. Sankey diagram visualizes the association between methylation status of deferentially methylated CpGs and plasma concentrations of chemical elements. The x-axis represents differentially methylated CpGs and chemical elements. The nodes on y-axis represent the positions of CpGs deferentially methylated in association with chemical elements, number of later is proportional to the size of each node and width of each arcBack to article page
