The temporal evolution of the average number of cumulative COVID-19 circumstances for treated regions and their corresponding synthetic control teams are proven in Fig. four C and D calculated on the idea of adjusted P values shown in Fig. 4 E and F point out that the estimated treatment results are not random for each samples. Obviously, the estimated distinction in COVID-19 improvement in Jena vis-à-vis the synthetic Jena is only convincing if 1) the requirements of the SCM are fulfilled and a pair of) probably concurrent policies other than masks can be dominated out. The second step also comprises distinction-in-distinction estimation as an additional test for latent concurrent policies that transcend observable insurance policies (displayed in SI Appendix, Fig. S2).

Average therapy effects for the introduction of face masks with a number of treated models. The figure reveals the typical improvement of the cumulative variety of COVID-19 cases for treated models , for his or her artificial control groups and estimated therapy effects.
