Figure 5.

Selective advantage of B.1.1.7 declines with increasing social restrictions in the UK.

The same data as in Figure 2 but now the selective advantage of B.1.1.7, as measured by the weekly change in log(frequency SGTF/frequency of non-SGTF), is plotted against the stringency index of restrictions during that week in the UK (taken from http://www.bsg.ox.ac.uk/research/research-projects/covid-19-government-response-tracker). All data points corresponding to a frequency of less than 10% were excluded to ensure SGTF data predominantly reflect the presence of B.1.1.7.
