188 modules associated with obesity, diabetes, hyperlipidemia, and hypertension. The vertical bars indicate the genes/diseases in the modules, the columns represent modules, and the rows represent the genes/diseases. The rows and columns are sorted in the ascending order by the score calculated by correspondence analysis (see Methods). Red, grey, blue, and green bars respectively indicate cliques that contain the hypertension, hyperlipidemia, obesity, and diabetes nodes. The letters 't,' 'l,' 'o,' and 'd' on the right show that in the literature the genes are related to hypertension, hyperlipidemia, obesity, and diabetes (see text for the literature references).
