In the version of this article initially published, there were errors in the 2nd paragraph of ‘Clinical assessments’ in the Methods section and in the legend of Supplementary figure 2, where the subtracted values appeared as ‘−30’ rather than ‘−7.’ The errors have been corrected in the HTML and PDF versions of the article.
