Spearman correlations between lowest traffic/mobility levels in New York counties shorty following PAUSE, and epidemic control by the end of our study.

As measures of epidemic control, we used the percent change in cumulative incidence %ΔCI and the change in smoothed daily % incidence Δ%DI, between the start of PAUSE and the end of our study. These were correlated with the lowest traffic level, as fraction of traffic baseline (top row), and with the lowest mobility levels to Retail, Grocery and Workspace (remaining three rows). The corresponding significance values are shown as separate columns.
