  1. aVariables used as active variables in the PCA. Density, transitivity, number of providers, number of links between providers and number of inpatient psychiatric beds in the index hospital were highly correlated; thus only density was introduced in the PCA. The proportion of nurses and the proportion of GPs among the healthcare providers of the network were highly correlated with the percentage of physicians among community-based health professionals in the network, and were therefore not introduced in the PCA. The proportion of psychiatrists among the healthcare providers of the network and the proportion of specialized health professionals among community-based health professionals were highly correlated with the number of psychiatrists in the network per 100,000 inhabitants, and were therefore not introduced in the PCA
