The temporal association of introducing and lifting non-pharmaceutical interventions with the time-varying reproduction number (R) of SARS-CoV-2: a modelling study across 131 countries

This modelling study, using data from 131 countries, found school closure, workplace closure, public events ban, requirements to stay at home, and internal movement limits were associated with a decreasing trend in the R ratio (significant only for the public events ban).
