Figure 6From: Discrete derivative: a data slicing algorithm for exploration of sharing biological networks between rheumatoid arthritis and coronary heart disease Graphics of initial data based on frequency with nodes in parenthesis. These networks are constructed with data set downloaded from PubMed on May 9, 2010. They are built under the conditions that any two nodes connected with each other by an edge are DescriptorName pairs on the co-occurrent frequencies. These frequencies can be demonstrated as integer which are greater equal than i, where i = 1, 2, 3,···, 30.Back to article page
