In the version of this article initially published, a composition error appeared in the second sentence of the Fig. 1 caption. In the text now reading “Microbial pathways related to short-chain fatty acid (SCFA) metabolism are already reduced and those related to branched-chain amino acid (BCAA) metabolism increased in metabolically matched controls relative to healthy controls, prior to IHD diagnosis,” the terms “reduced” and “increased” were reversed. The error has been corrected in the HTML and PDF versions of the article.
