Vertical dashed traces indicate the time corridor by which the respective therapy periods start. Again, vertical dashed traces point out the time hall by which the respective treatment periods start. As for the case of placebo-in-area tests, it is necessary for the validity of results that we do not observe vital remedy effects for Jena prior to the introduction of face masks on 6 April or its announcement on 30 March. To rule out such anticipation results, we now have systematically reviewed all basic decrees printed by the local administration in Jena.
It’s too late now for anything but stopping as much particular person-to-particular person interplay as attainable. A affordable evaluation of the literature on the effectiveness of sporting masks in stopping the spread of the Corona virus would provide an account of the methodology used to conduct the search and screen potential articles.

2 point out that the discount within the reported number of COVID-19 instances in Jena clearly exceeds the trend in most different areas—each for the general pattern in Fig. 2A and the subsample of huge cities (kreisfreie Städte) in Fig. We also take a look at for the sensitivity of the estimated therapy effects to changes in the set of time-fixed predictors. We accomplish that by sequentially excluding particular person variables from the set of predictors. As shown in SI Appendix, section C.7, the estimated trajectories for the respective synthetic control groups comply with a really similar trend.
