A Smoothed importation frequency (SIF) values over time. The gray area represents 95% HPD from 2000 Bayesian posterior samples, while the blue line depicts the SIF values derived from the MCC tree. B Change rate of SIF over time calculated from the MCC tree. Red vertical bars indicate the implementation date of the twelve major NPIs in the country, and their heights represent the effectiveness metric for that day. C NPI effectiveness for Germany overall, as well as for North Rhine-Westphalia, Bavaria, Baden-Württemberg, and Saxony.
