- Condition The experimental condition / phenotype studied according to the Experimental Factor Ontology
- 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
- SES score below median score of 6.4 based on (a) residential SES rank; (b) the number of paternal schooling years; and (c) household crowding index.

Signature 1
Source: Figure 2D;
Description: Figure 2D. A heatmap of the multivariable model describing the top 50 associations between the independent variables and bacterial features. Positive associations are colored in red, while inverse associations are colored in blue. The color gradient represents the strength of the association (the effect size), with darker colors representing the stronger associations. The effect size was calculated by the following formula: (−log(qval)*SIGN (coeff)).
Abundance in Group 1: increased abundance in Low SES
