Bacterial operational taxonomic units (OTUs) associated with coprostanol total ion current.

For each OTU, the taxonomy (u = uncultured), Spearman correlation coefficient (rs), relative abundance (RA) and relative frequency (RF) based on 16S rRNA sequence reads are shown. A reference OTU (refOTU) sequence accession number from the Silva (release 108) database is shown for all uncultured species. Superscripts after the OTU number indicate whether the species is an indicator species for a specific cohort. HAbx: healthy subjects with prior antibiotic exposure, H: healthy subjects with no prior antibiotic exposure; Vanc: subjects with CDI who received vancomycin therapy. P-values are shown with Bonferroni correction.
