(Cell Reports 33, 108331, November 3, 2020) In the originally published version of this article, due to a data input error, one of the participants in the MARS cohort, participant 0064, was inadvertently categorized as a healthy child in Figure S7 and Tables 1 and S3 instead of as a healthy adult. In addition, in Figures S7C, S7D, and S7E, only a subset of the complete 16S rRNA dataset was shown. The corrected versions of Tables 1 and S3 now appear with the article online. The original and corrected version of Figure S7 appears here. The re-analysis of the corrected dataset does not change the original interpretation of data or conclusions reported in the paper. The authors regret this error.
