English: The odds ratio (left y axis) of B.1.1.7 versus 'wild' variants is expected to grow exponentially; [0.076] means 7.9% growth per day. Dataset dates are publication dates. 'seq' for data from genomic sequnecing; 'SGTF' for PCR-based data (S-Gene Target Failure; less accurate than sequencing), and PCR for a PCR test specifically designed to detect the VOC (Switzerland only). To convert the log slope ${\displaystyle s}$ to ratios of reproduction numbers: ${\displaystyle R_{\mathrm {VOC} }/R_{\mathrm {other} }=\exp(s\,T_{g})}$ with ${\displaystyle T_{g}}$ the generation interval (usually assumed 4–6 days). The daily growth factor is ${\displaystyle \exp(s\cdot (1~\mathrm {d} ))}$. Data sources: DK^[1], NL^[2][3][4][5], PT^[6], CH^[7], UK^[8], IE^[9][10][11].

The logarithmic slopes as indicated are not based on a rigorous uncertainty analysis. Code to generate these graphs: Github/han-kwang.
