Figure 8. — Plasma metabolomics associated with serum ferritin, executive function, and semantic memory in women. Boxplots of the normalized variable importance measure (VIM) (a and c) and SHAP summary plots (b and d), for the metabolites associated with the serum ferritin levels measured by HPCL-ESI-MS/MS in positive (a) and negative (c) models. (e and f) Heatmap displaying the Spearman correlation (adjusted by age, body mass index, and education years) between PVF, SVF, and TDS and the plasma metabolomics in positive mode (e) and negative mode (f). Significant associations are shown with a cross: **** <0.001, ***<0.01, **<0.05, *<0.1. PVF, phonemic verbal fluency; SVF, semantic verbal fluency; TDS, total digit span.
