Note. TB = tuberculosis. The network metrics in this table quantify the visual information of Figure 3 ▶ and were used to develop and identify the cases and contacts identified as high priorities on the basis of high scores for reach, degree, and betweenness. For example, nodes 1833, 2034, and 1239 (surrounded by dashed-line boxes in Figure 3 ▶) were identified as important contacts for screening and evaluation because of their high betweenness scores in this table.

^aNodes numbered between 1 and 35 represent TB patients; nodes with numbers greater than 1000 represent named contacts.
