First passage times (in days) to selected cities, assuming the epidemic originated on January 1 in Hong Kong.

A double dash means that the city is not present in the sample. For each city in each sample, we computed the difference in the first passage times between the model based on the sample and the model based on the entire network. If this difference was 7 days or larger (6 days was the largest standard deviation), we used bold font in that cell.
