Fig. 1From: The translational network for metabolic disease – from protein interaction to disease co-occurrenceChanges in network density by a q-step walk on the PPI network: The amount of connections for disease-disease association increases as the step size q increases. With rich connections among diseases, the chances of having inferences for most diseases, including rare diseases, are increased because it enables us to use the information propagated from other diseases through the connectionsBack to article page
