Correction of the 'distance_popdensityagegroups_null_35.csv’ and ‘dis…

…tance_popdensityagegroups_null_120.csv’ files that were identical to each other. These files included median distances to the Huanan market of locations drawn from a Wuhan population density map, as described in our paper. Upon inspection of these files, we further noticed that the number of pseudoreplicates contained in them, and in one additional file (‘distance_popdensityagegroups_null_155.csv’), was 10,000 rather than the n = 1000 used for all related analyses. Therefore ‘distance_popdensityagegroups_null_155.csv’ was also updated to contain 1000 median distances. This has no impact on the results as all p-values remain p < 0.001 (and p = 0.003 using the Benjamini-Hochberg procedure).
