The authors regret that there were errors in the footnotes of Table 1–4 in the main article. The tables with their corrected footnotes are presented below, and the changes displayed also apply to any subsequent mention of these values in the text. The authors confirm that these changes have no effect on the results or conclusions presented in this article.
