Network centrality for the identification of biomarkers in respondent-driven sampling datasets

Abstract: Networks science techniques are frequently used to provide meaningful insights into the populations underlying medical and social data. This paper examines SATHCAP, a dataset related to HIV and drug use in three US cities. In particular, we use network measures such as betweenness centrality, closeness centrality, and eigenvector centrality to find central, important nodes in a network derived from SATHCAP data. We evaluate the attributes of these important nodes and create an exceptionality score based on the… Show more

“…The SATHCAP data are robust and lend themselves to many types of analysis. For example, the data can be subjected to standard statistical analysis [ 12 , 13 ], the referral chains can be interpreted as complex networks [ 14 ], and the survey design itself can be used to learn more about RDS [ 15 ]. SATHCAP is used here because of previous successful application to a similar dataset [ 16 ].…”

“…Degree centrality (DC) is a whole-brain connectivity index that describes the global features of a given node through the use of graph theory models to assess the functional connectivity between that node and nodes throughout the brain ( 18 ). DC-based analytical approaches have recently been used to successfully evaluate patients diagnosed with schizophrenia, depression, and mild cognitive impairment ( 19 21 ).…”
