Figure 4. Personal network structure for two patients with stroke.

Figure 4

The structure of a network is the organization of ties and their patterns in quantitative terms. Patients who are at risk of poor outcomes are typically surrounded by a small number of close-knit alters. a | Patient 1 has a high-constraint network in which all members are closely knit together. b | Patient 2 has a low-constraint network that includes unconnected individuals and structural holes.
