 A) Pairwise trace element intersections accounting for mutual shared interactions with glaucoma-related genes. The matrix is symmetrical regarding the gray diagonal. A yellow color gradient is employed to indicate trace elements with higher number of shared interactions with coding genes. Also, columns and rows indicate in brackets the total number of interactions for each trace element. B) Venn diagram depicting the number of shared genes between six distinct trace elements. Chromium and iron are not shown due to their low number of interactions with the selected genes
