Heatmap of Inter-associations between 52 Organs. x-axis and y-axis are both 52 organs. The degrees of redness and blackness in each cell represent increase of association between organs. The legend above the heatmap indicates the range of association between organs. The association between organs is expressed by 1 minus log10 of p-value. It is nonlinear color scale from white to red to black, correspondingly, indicating the value of 1-log10(p-value) scales from 1 to 7.6.
