Time-related, NPI-independent effects as identified by the model. The panels show the predicted growth rate given the two time-related, but NPI-independent covariates that were used in the analysis. The panel on the left shows an absolute time scale, indicating the timing in the global COVID-19 outbreak (measured in relation to March 11, 2020, the day the WHO declared COVID-19 a pandemic). The panel on the right is a relative time scale within each country. It indicates how recent an outbreak is within that country (measured in relation to the day that 25 cumulative COVID-19 cases were reached). The dark brown line is the median effect over all bootstrap samples, grey lines depict individual bootstrap samples, and the light brown line represents the complete training set
