Estimate Std. err. p-value
HRR (South Bend) without adjusting for network measures −1.09 0.306 <0.0001
Estimate Std. err. p-value
HRR (South Bend) −0.677 0.494 0.171
Physician node strength 0.005 0.003 0.050
Physician weighted closeness centrality 0.157 0.264 0.551
Hospital weighted closeness centrality 0.384 0.286 0.178
Estimate Std. err. p-value
HRR (South Bend) −0.825 0.618 0.182
Physician node strength 0.005 0.003 0.096
Physician weighted closeness centrality 0.136 0.307 0.656

Note: The model estimates, standard errors (std. err.) and p-values for models adjusting only for patient characteristics (top), and then also for physician and hospital centrality (middle) and physician and hospital centrality and family practice homophily (bottom) are shown.
