Correction to: Nature Aging https://doi.org/10.1038/s43587-022-00193-0, published online 14 April 2022.

In the version of this article initially published, three errors were present. In the fourth sentence of the Results, now reading “A. putredinis is a moderately abundant species (approximately 0.3% relative abundance in both generations)...,” the relative abundance first appeared as “6.0.” Corresponding data in Supplementary Table 2 have also been updated and replaced to reflect correct abundance values. In the penultimate sentence of the Results, “Gut microbes involved in bile acid metabolism of old people” subsection, in the text now reading “GDCA is an intermediate linking glycocholic acid (GCA),” “glycocholic” replaces “glycodeoxycholic.” Further, in the second paragraph of Methods, in the text reading, in part, “A questionnaire … was used to generate the metadata of 92 socioeconomic, lifestyle and medical (SLM) factors,” “SLM” is now defined. The changes have been made in the HTML and PDF versions of the article.
