Correction to: Nature Communications, published online 8 February 2021.

The original version of this Article contained errors in the figure legends for Figs. 1 and 2. Both of the legends incorrectly defined the whiskers of the box plots as representing “95% confidence intervals”. This has been corrected to “whiskers indicate the 1.5 interquartile range”.

This error has been corrected in both the PDF and HTML versions of the Article.
