Figure 2

Causal association heatmap of serum metabolites with sepsis and 28-day mortality in sepsis by IVW analysis. Rows in the figure represent different serum metabolites, while columns depict two outcomes: sepsis and 28-day mortality in sepsis. Different metabolites are presented in distinct colors, with pink and blue indicating positive and negative factors, respectively. Deeper colors on the heatmap signify higher significance.
