The original version of this article includes Manuela Raffatellu, Pieter C. Dorrestein, and Rob Knight as authors. These authors do not feel they contributed substantially to the paper, did not read or approve the manuscript, and wish to have their names removed. The corresponding authors apologize for this mistake but thank these individuals for performing the DNA extraction, shotgun metagenomic DNA sequencing, metabolite extraction, and LC-MS/MS analysis. All authors agree to this change of authorship, and the conclusions of the paper have not changed.
In addition, text edits to the STAR Methods section have been made to enhance clarity, and the shotgun sequencing datasets reported in the original paper have been transferred from http://ncbo.nlm.nih.gov/bioproject/632613 to the European Genome-Phenome Archive (EGAS000010046), which the authors feel affords better security for patient confidentiality.
