Volcano plots of P-values and β coefficients for the association between individual metabolites and DASH diets
The red horizontal dashed line represents the Bonferroni-adjusted threshold (5.33 × 10−5) and the red vertical dashed line is set at β coefficient=0. Positive β coefficients (to the right of the red vertical dashed line) indicate that the level of metabolites was higher in individuals randomly assigned to DASH diet relative those assigned to the control diet. Negative β coefficients (to the left of the red vertical dashed line) indicate that the level of metabolites was lower in individuals randomly assigned to DASH diet relative those assigned to the control diet. The top 10 metabolites representative of the DASH-high sodium diet and DASH-low sodium diet relative to the control-high sodium diet are labeled.
