Signature 1
Source: FIGURE 3
Description: Scatter-plot of neighborhood SES and bacterial genera. Figs depict associations between neighborhood SES and Prevotella to Bacteroides ratio (upper panel), as well as the relative abundance of Prevotella (middle panel) and Bacteroides (lower panel). Specimens are biopsies excised from sigmoid mucosa.
