Closeness centrality	4.14 ± 5.50	0.75	0.456

All models include as a covariate the year of arrival of the plague to each city. It is shown the outcome from the complete network and from the networks built using only trading and pilgrimage links, respectively. Transitivity in the pilgrimage network could not be calculated because all the triples were open.
