We estimate remedy effects from introducing face masks via the SCM for single and multiple treated items. (All analyses are undertaken in Stata. The corresponding files plus data are available in SI Appendix.) The SCM has turn out to be more and more well-liked for policy evaluations that rely on comparative case research. The intuition of SCM estimation can briefly be described as follows (see ref. 2⇓⇓–5 and SI Appendix, part B for extra background). This timing effect might also clarify the distinction between Jena estimates and lower estimates for other areas.

As this temporal transmission channel seems plausible given a median time lag between infection and registration of just about equal length, we take this as first proof for a face masks impact within the discount of SARS-CoV-2 infections. 1A clearly shows a gradually widening gap in the cumulative number of COVID-19 cases between Jena and its artificial control group. The size of the effect 20 d after the beginning of the therapy quantities to a lower in the number of cumulative COVID-19 instances of 23%, which corresponds to a drop in newly registered instances of roughly 75%. Expressed differently, the day by day progress rate of the variety of infections decreases by 1.28 percentage factors per day (see SI Appendix, section D.2 for computational details and an overview of all measures).
