Network Metrics for Three Units With Highest and Lowest Fall Rates.

Unit	Node Size	Diffusion	Average Distance	Density	Weighted Density	Total Degree Centrality	Betweenness Centrality	Eigenvector Centrality	Clustering Coefficient
1	25	.74	.69	.29	.17	.18	.03	.26	.42
8	9	.75	.45	.51	.37	.39	.04	.39	.55
16	17	.81	.57	.5	.3	.31	.03	.33	.59

Note. Units 8 (hybrid racetrack) and 16 (centralized compact square) had no falls. Unit 1 (decentralized cross) had an average rate of 4.94 falls per 1,000 patient days.
