Figure 1. Combined network of morphological MRI, biomechanics, compositional MRI, and bone shape analysis.
Each circle, or ‘node’, represents a subject or a collection of subjects. If two subjects are similar they are put together in the same node and if two nodes have enough in common they are connected by a line, or an ‘edge.’ The proximity of each node to another as well as the number of edges between two nodes represents the relative similarity of the subjects contained in each node. This network is color coded by subjects per node: Single subject nodes are expressed in blue and scale upwards towards red if a node has more subjects.
