Summary SHAP plot of the 20 most influential bacterial genera in the XGBoost model. Each point represents one sample, with color indicating the normalized abundance of each genus (yellow = low, purple = high). The x-axis shows the SHAP value, reflecting the direction and magnitude of each feature’s impact on the model output. Positive SHAP values indicate higher associated predicted probability of metabolic syndrome, while negative values indicate lupus. The genus Alistipes (mean |SHAP|= 0.416) showed lower abundances associated with the metabolic syndrome group.
