- socioeconomic statussocioeconomic status
- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- High SES
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Low SES
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- 44 healthy participants from low-income neighborhoods with a median annual income of $20,100 and a 35% unemployment rate and neighborhoods at the high end, with a median income of $129,570 and an unemployment rate under 5%).
(Income level as a continuous variable.)

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.
